The Issue Presented
Domestic courts frequently apply foreign law. For example, the forum's choice-of-law rules may require a court to apply foreign law, or a party may expressly base a claim or defense on foreign law. Private international law (or “conflict of laws”) provides principles governing many aspects of the way courts should identify and interpret foreign law.Footnote 1
In the U.S. federal courts, the applicable rule is Rule 44.1 of the Federal Rules of Civil Procedure, which provides, in relevant part, “In determining foreign law, the court may consider any relevant material or source, including testimony, whether or not submitted by a party or admissible under the Federal Rules of Evidence. The court's determination must be treated as a ruling on a question of law.”Footnote 2 However, those principles do not provide clear guidance on how heavily a court should weigh a foreign government's own statements about the meaning of its law.Footnote 3 This was the issue presented in Animal Science Products, Inc. v. Hebei Welcome Pharmaceutical Co. Ltd (Animal Science). Footnote 4
The Animal Science Litigation
In Animal Science, petitioners alleged that the respondents conspired to fix the price of vitamin C exports to the United States in violation of U.S. antitrust law. Respondents raised various defenses based on the assertion that their price-fixing was required by Chinese law.Footnote 5 In support of the respondents, the Ministry of Commerce of the People's Republic of China filed statements asserting that the alleged conspiracy was instead “a regulatory pricing regime mandated by the government of China.”Footnote 6 The petitioners challenged this position, noting that the Ministry identified no written law expressly requiring respondents to fix vitamin C export prices, and that China had previously made a statement to the World Trade Organization (WTO) that it “gave up export administration of … vitamin C” in 2002.Footnote 7
In rejecting the respondents' argument and holding that Chinese law did not require them to fix prices, the District Court provided one possible answer to the question of foreign government statements regarding the meaning of foreign law: such statements are “entitled to substantial deference, but will not be taken as conclusive evidence.”Footnote 8
The U.S. Court of Appeals for the Second Circuit reversed the District Court's decision, offering an alternative rule: “[W]hen a foreign government, acting through counsel or otherwise, directly participates in U.S. court proceedings by providing a sworn evidentiary proffer regarding the construction and effect of its laws and regulations, which is reasonable under the circumstances presented, a U.S. court is bound to defer to those statements.”Footnote 9
An amicus brief filed with the Supreme Court proposed a third approach: “U.S. courts should give respectful consideration to a foreign government's statements about its law. But as a matter of law, a foreign government's statements cannot be binding on U.S. courts. Instead, U.S. courts should accurately and independently determine the meaning of foreign law taking into account not only the foreign government's own statements, but also other relevant information about that law.”Footnote 10
The Supreme Court's Decision
The Supreme Court vacated the Second Circuit's decision, unanimously holding that a “federal court should accord respectful consideration to a foreign government's submission, but is not bound to accord conclusive effect to the foreign government's statements.”Footnote 11
What, then, does it mean to give “respectful consideration” to foreign government statements? The Supreme Court affirmed that “a federal court should carefully consider a foreign state's views about the meaning of its own laws”;Footnote 12 however, it emphasized that “the appropriate weight in each case will depend upon the circumstances,” and it explained that “[r]elevant considerations include the statement's clarity, thoroughness, and support; its context and purpose; the transparency of the foreign legal system; the role and authority of the entity or official offering the statement; and the statement's consistency with the foreign government's past positions.”Footnote 13 The Court also identified warning signs for courts to be alert to, noting that “[w]hen a foreign government makes conflicting statements … or … offers an account in the context of litigation, there may be cause for caution in evaluating the foreign government's submission.”Footnote 14
Assessment and Implications
The Supreme Court's approach is a sensible one. Unlike the Second Circuit's “bound to defer” rule, the “respectful consideration” standard does not prevent U.S. federal courts from “consider[ing] any relevant material or source” when determining foreign law, as Rule 44.1 expressly authorizes them to do.Footnote 15 Respectful consideration is also consistent with the principle of accuracy in the determination of foreign law, which implies that courts must consider information about foreign law based on how reliable and persuasive the information is,Footnote 16 and with the principle that U.S. courts should determine law—including foreign law—independently.Footnote 17
The “respectful consideration” standard is also consistent with the principal international treaties on the interpretation of foreign law:Footnote 18 the European Convention on Information on Foreign LawFootnote 19 and the Inter-American Convention on Proof of and Information on Foreign Law.Footnote 20 Both treaties allow a court to request information about foreign law from a designated foreign government official. But even when there is a formal request and foreign government reply, the reply is not binding on the court.Footnote 21 Thus, the U.S. Supreme Court's Animal Science opinion may be informative for the courts of other countries when ascertaining the content and meaning of foreign law.
Although it rejected the Second Circuit's bound-to-defer rule, the Supreme Court's opinion does not imply that statements by foreign governments about foreign law are unimportant. To the contrary, one would expect that courts applying the respectful consideration standard will in many cases rely heavily on such statements.Footnote 22 Ordinarily, a U.S. court applying the respectful consideration standard would likely follow an independent foreign court's authoritative interpretation of its own law in an unrelated case. Courts faced with issues of foreign law should welcome—and in some cases actively seek—information from a foreign state about its law.Footnote 23 The contribution of the Animal Science decision is not to diminish the importance of foreign government statements about foreign law, but rather to clarify that a court is not required to treat those statements as conclusive and to provide factors to consider when determining how much weight to give to those statements.

Syllabus
ANIMAL SCIENCE PRODUCTS, INC., et al. v. HEBEI WELCOME PHARMACEUTICAL CO. LTD. et al.
certiorari to the united states court of appeals for the second circuit
No. 16–1220. Argued April 24, 2018—Decided June 14, 2018
Petitioners, U. S.-based purchasers of vitamin C (U. S. purchasers), filed a class-action suit, alleging that four Chinese corporations that manufacture and export the nutrient (Chinese sellers), including the two respondents here, had agreed to fix the price and quantity of vitamin C exported to the United States, in violation of §1 of the Sherman Act. The Chinese sellers moved to dismiss the complaint on the ground that Chinese law required them to fix the price and quantity of vitamin C exports, thus shielding them from liability under U. S. antitrust law. The Ministry of Commerce of the People's Republic of China (Ministry) filed an amicus brief in support of the motion, explaining that it is the administrative authority authorized to regulate foreign trade, and stating that the alleged conspiracy in restraint of trade was actually a pricing regime mandated by the Chinese Government. The U. S. purchasers countered that the Ministry had identified no law or regulation ordering the Chinese sellers' price agreement, highlighted a publication announcing that the Chinese sellers had agreed to control the quantity and rate of exports without government intervention, and presented supporting expert testimony.
The District Court denied the Chinese sellers' motion in relevant part, concluding that it did not regard the Ministry's statements as “conclusive,” particularly in light of the U. S. purchasers' evidence. When the Chinese sellers subsequently moved for summary judgment, the Ministry submitted another statement, reiterating its stance, and the U. S. purchasers pointed to China's statement to the World Trade Organization that it ended its export administration of vitamin C in 2002. The court denied this motion as well. The case was then tried to a jury, which returned a verdict for the U. S. purchasers.
The Second Circuit reversed, holding that the District Court erred by denying the Chinese sellers' motion to dismiss the complaint. When a foreign government whose law is in contention submits an official statement on the meaning and interpretation of its domestic law, the court concluded, federal courts are “bound to defer” to the foreign government's construction of its own law, whenever that construction is “reasonable.” Inspecting only the Ministry's brief and the sources cited therein, the court found the Ministry's account of Chinese law “reasonable.”
Held: A federal court determining foreign law under Federal Rule of Civil Procedure 44.1 should accord respectful consideration to a foreign government's submission, but the court is not bound to accord conclusive effect to the foreign government's statements.
Rule 44.1 fundamentally changed the mode of determining foreign law in federal courts. Before adoption of the rule in 1966, a foreign nation's laws had to be “proved as facts.” Talbot v. Seeman, 1 Cranch 1, 38. Rule 44.1, in contrast, specifies that a court's determination of foreign law “must be treated as a ruling on a question of law.” And in ascertaining foreign law, courts are not limited to materials submitted by the parties, but “may consider any relevant material or source.” Appellate review, as is true of domestic law determinations, is de novo. The purpose of these changes was to align, to the extent possible, the process for determining alien law and the process for determining domestic law.
Neither Rule 44.1 nor any other rule or statute addresses the weight a federal court determining foreign law should give to the views presented by a foreign government. In the spirit of “international comity,” Société Nationale Industrielle Aérospatiale v. United States Dist. Court for Southern Dist. of Iowa, 482 U. S. 522, 543, and n. 27, a federal court should carefully consider a foreign state's views about the meaning of its own laws. The appropriate weight in each case, however, will depend upon the circumstances; a federal court is neither bound to adopt the foreign government's characterization nor required to ignore other relevant materials. No single formula or rule will fit all cases, but relevant considerations include the statement's clarity, thoroughness, and support; its context and purpose; the transparency of the foreign legal system; the role and authority of the entity or official offering the statement; and the statement's consistency with the foreign government's past positions.
Judged in this light, the Second Circuit's unyielding rule is inconsistent with Rule 44.1 and, tellingly, with this Court's treatment of analogous submissions from States of the United States. If the relevant state law is established by a decision of “the State's highest court,” that decision is “binding on the federal courts,” Wainwright v. Goode, 464 U. S. 78, 84, but views of the State's attorney general, while attracting “respectful consideration,” do not garner controlling weight, Arizonans for Official English v. Arizona, 520 U. S. 43, 76–77, n. 30. Furthermore, because the Second Circuit riveted its attention on the Ministry's submission, it did not address evidence submitted by the U. S. purchasers. The court also misperceived the pre-Rule 44.1 decision of United States v. Pink, 315 U. S. 203. Under the particular circumstances of that case, this Court found conclusive a declaration from the government of the Russian Socialist Federal Soviet Republic on the extraterritorial effect of a decree nationalizing assets: The declaration was obtained by the United States through official “diplomatic channels,” id., at 218; there was no indication that the declaration was inconsistent with the Russian Government's past statements; and the declaration was consistent with expert evidence in point.
The Second Circuit expressed concern about reciprocity, but the United States has not historically argued that foreign courts are bound to accept its characterizations or precluded from considering other relevant sources. International practice is also inconsistent with the Second Circuit's rigid rule. Pp. 7–12.
837 F. 3d 175, vacated and remanded.
Ginsburg, J., delivered the opinion for a unanimous Court.

No. 16–1220
ANIMAL SCIENCE PRODUCTS, INC., et al., PETITIONERS v. HEBEI WELCOME PHARMACEUTICAL CO. LTD., et al.
onwrit ofcertiorari to theunitedstatescourt ofappeals for the second circuit
[June 14, 2018]
Justice Ginsburg delivered the opinion of the Court.
When foreign law is relevant to a case instituted in a federal court, and the foreign government whose law is in contention submits an official statement on the meaning and interpretation of its domestic law, may the federal court look beyond that official statement? The Court of Appeals for the Second Circuit answered generally “no,” ruling that federal courts are “bound to defer” to a foreign government's construction of its own law, whenever that construction is “reasonable.” In re Vitamin C Antitrust Litigation, 837 F. 3d 175, 189 (2016).
We hold otherwise. A federal court should accord respectful consideration to a foreign government's submission, but is not bound to accord conclusive effect to the foreign government's statements. Instead, Federal Rule of Civil Procedure 44.1 instructs that, in determining foreign law, “the court may consider any relevant material or source . . . whether or not submitted by a party.” As “[t]he court's determination must be treated as a ruling on a question of law,” Fed. Rule Civ. Proc. 44.1, the court “may engage in its own research and consider any relevant material thus found,” Advisory Committee's 1966 Note on Fed. Rule Civ. Proc. 44.1, 28 U. S. C. App., p. 892 (hereinafter Advisory Committee's Note). Because the Second Circuit ordered dismissal of this case on the ground that the foreign government's statements could not be gainsaid, we vacate that court's judgment and remand the case for further consideration.
I
Petitioners, U. S.-based purchasers of vitamin C (hereinafter U. S. purchasers), filed a class-action suit against four Chinese corporations that manufacture and export the nutrient (hereinafter Chinese sellers). The U. S. purchasers alleged that the Chinese sellers, two of whom are respondents here, had agreed to fix the price and quantity of vitamin C exported to the United States from China, in violation of §1 of the Sherman Act, 15 U. S. C. §1. More particularly, the U. S. purchasers stated that the Chinese sellers had formed a cartel “facilitated by the efforts of their trade association,” the Chamber of Commerce of Medicines and Health Products Importers and Exporters (Chamber). Complaint in No. 1:05–CV–453, Docket No. 1, ¶43. The Judicial Panel on Multidistrict Litigation consolidated the instant case and related suits for pretrial proceedings in the United States District Court for the Eastern District of New York.
The Chinese sellers moved to dismiss the U. S. purchasers' complaint on the ground that Chinese law required them to fix the price and quantity of vitamin C exports. Therefore, the Chinese sellers urged, they are shielded from liability under U. S. antitrust law by the act of state doctrine, the foreign sovereign compulsion doctrine, and principles of international comity. The Ministry of Commerce of the People's Republic of China (Ministry) filed a brief as amicus curiae in support of the Chinese sellers' motion. The Ministry's brief stated that the Ministry is “the highest administrative authority in China authorized to regulate foreign trade,” App. to Pet. for Cert. 190a; that the Chamber is “an entity under the Ministry's direct and active supervision” and is authorized to regulate vitamin C exports, id., at 196a; and that the conspiracy in restraint of trade alleged by the U. S. purchasers was in fact “a regulatory pricing regime mandated by the government of China,” id., at 197a.Footnote 1
In response, the U. S. purchasers disputed that Chinese law required the Chinese sellers to engage in price fixing. Among other things, the U. S. purchasers noted that the Ministry had not identified any written law or regulation expressly ordering the Chinese sellers' price agreement.Footnote 2 They also highlighted a Chamber announcement that the manufacturers “were able to reach a self-regulated agreement . . . whereby they would voluntarily control the quantity and pace of exports . . . without any government intervention.” App. 109. In addition, the U. S. purchasers presented expert testimony that the Chinese Government's authorization of a Vitamin C Subcommittee within the Chamber did not necessarily mean that the subcommittee's price fixing was mandated by law.
The District Court denied the Chinese sellers' motion to dismiss the complaint in relevant part. In re Vitamin C Antitrust Litigation, 584 F. Supp. 2d 546, 559 (EDNY 2008). That court acknowledged that the Ministry's amicus brief was “entitled to substantial deference.” Id., at 557. The court, however, did not regard the Ministry's statements as “conclusive,” emphasizing particularly that the U. S. purchasers had submitted evidence suggesting that the price fixing was voluntary. Ibid. The record, the District Court determined, was “too ambiguous to foreclose further inquiry into the voluntariness of [the Chinese sellers'] actions.” Id., at 559.
After further discovery, focused on whether Chinese law compelled the Chinese sellers to enter into a price-fixing agreement, the Chinese sellers moved for summary judgment. See In re Vitamin C Antitrust Litigation, 810 F. Supp. 2d 522, 525–526 (EDNY 2011). The Ministry submitted an additional statement, reiterating that “the Ministry specifically charged the Chamber . . . with the authority and responsibility . . . for regulating, through consultation, the price of vitamin C manufactured for export.” App. 133. The Chinese sellers tendered expert testimony in accord with the Ministry's account, which stressed that the Ministry's “interpretation of its own regulations and policies carries decisive weight under Chinese law.” Id., at 142. The U. S. purchasers, in response, cited further materials supporting their opposing view, including China's statement to the World Trade Organization (WTO) that it “gave up export administration of . . . vitamin C” in 2002. 810 F. Supp. 2d, at 532 (internal quotation marks omitted). Denying the Chinese sellers' motion for summary judgment, the District Court held that Chinese law did not require the sellers to fix the price or quantity of vitamin C exports. Id., at 525.
The case was then tried to a jury, which returned a verdict for the U. S. purchasers. The jury found that the Chinese sellers had agreed to fix the prices and quantities of vitamin C exports, see App. to Pet. for Cert. 276a–279a, and further found that the Chinese sellers were not “actually compelled” by China to enter into those agreements, id., at 278a. In accord with the jury's verdict, the District Court entered judgment for the U. S. purchasers, awarding some $147 million in treble damages and enjoining the Chinese sellers from further violations of the Sherman Act.
The Court of Appeals for the Second Circuit reversed, holding that the District Court erred in denying the Chinese sellers' motion to dismiss the complaint. In re Vitamin C Antitrust Litigation, 837 F. 3d 175, 178, 195–196 (2016). The Court of Appeals determined that the propriety of dismissal hinged on whether the Chinese sellers could adhere to both Chinese law and U. S. antitrust law. See id., at 186. That question, in turn, depended on “the amount of deference” owed to the Ministry's characterization of Chinese law. Ibid. Cognizant of “competing authority” on this question, ibid., the Court of Appeals settled on a highly deferential rule: “[W]hen a foreign government, acting through counsel or otherwise, directly participates in U. S. court proceedings by providing a [statement] regarding the construction and effect of [the foreign government's] laws and regulations, which is reasonable under the circumstances presented, a U. S. court is bound to defer to those statements,” id., at 189. The appeals court “note[d] that[,] if the Chinese Government had not appeared in this litigation, the [D]istrict [C]ourt's careful and thorough treatment of the evidence before it in analyzing what Chinese law required at both the motion to dismiss and summary judgment stages would have been entirely appropriate.” Id., at 191, n. 10.
Applying its highly deferential rule, the Court of Appeals concluded that the Ministry's account of Chinese law was “reasonable.” In so concluding, the Court of Appeals inspected only the Ministry's brief and sources cited therein. Id., at 189–190. Because it thought that “a U. S. court [must] not embark on a challenge to a foreign government's official representation,” id., at 189, the Court of Appeals disregarded the submissions made by the U. S. purchasers casting doubt on the Ministry's account of Chinese law, id., at 189–190. Based solely on the Ministry's statements, the Court of Appeals held that “Chinese law required [the Chinese sellers] to engage in activities in China that constituted antitrust violations here in the United States.” Ibid.
We granted certiorari to resolve a Circuit conflict over this question: Is a federal court determining foreign law under Rule 44.1 required to treat as conclusive a submission from the foreign government describing its own law? 583 U. S.—(2018).Footnote 3
II
At common law, the content of foreign law relevant to a dispute was treated “as a question of fact.” Miller, Federal Rule 44.1 and the “Fact” Approach to Determining Foreign Law: Death Knell for a Die-Hard Doctrine, 65 Mich. L. Rev. 613, 617–619 (1967) (Miller). In 1801, this Court endorsed the common-law rule, instructing that “the laws of a foreign nation” must be “proved as facts.” Talbot v. Seeman, 1 Cranch 1, 38 (1801); see, e.g., Church v. Hubbart, 2 Cranch 187, 236 (1804) (“Foreign laws are well understood to be facts.”). Ranking questions of foreign law as questions of fact, however, “had a number of undesirable practical consequences.” 9A C. Wright & A. Miller, Federal Practice and Procedure §2441, p. 324 (3d ed. 2008) (Wright & Miller). Foreign law “had to be raised in the pleadings” and proved “in accordance with the rules of evidence.” Ibid. Appellate review was deferential and limited to the record made in the trial court. Ibid.; see also Miller 623.
Federal Rule of Civil Procedure 44.1, adopted in 1966, fundamentally changed the mode of determining foreign law in federal courts. The Rule specifies that a court's determination of foreign law “must be treated as a ruling on a question of law,” rather than as a finding of fact.Footnote 4 Correspondingly, in ascertaining foreign law, courts are not limited to materials submitted by the parties; instead, they “may consider any relevant material or source . . . , whether or not . . . admissible under the Federal Rules of Evidence.” Ibid. Appellate review, as is true of domestic law determinations, is de novo. Advisory Committee's Note, at 892. Rule 44.1 frees courts “to reexamine and amplify material . . . presented by counsel in partisan fashion or in insufficient detail.” Ibid. The “obvious” purpose of the changes Rule 44.1 ordered was “to make the process of determining alien law identical with the method of ascertaining domestic law to the extent that it is possible to do so.” Wright & Miller §2444, at 338–342.
Federal courts deciding questions of foreign law under Rule 44.1 are sometimes provided with the views of the relevant foreign government, as they were in this case through the amicus brief of the Ministry. See supra, at 2–3. As the Court of Appeals correctly observed, Rule 44.1 does not address the weight a federal court determining foreign law should give to the views presented by the foreign government. See 837 F. 3d, at 187. Nor does any other rule or statute. In the spirit of “international comity,” Société Nationale Industrielle Aérospatiale v. United States Dist. Court for Southern Dist. of Iowa, 482 U. S. 522, 543, and n. 27 (1987), a federal court should carefully consider a foreign state's views about the meaning of its own laws. See United States v. McNab, 331 F. 3d 1228, 1241 (CA11 2003); cf. Bodum USA, Inc. v. La Cafetière, Inc., 621 F. 3d 624, 638–639 (CA7 2010) (Wood, J., concurring). But the appropriate weight in each case will depend upon the circumstances; a federal court is neither bound to adopt the foreign government's characterization nor required to ignore other relevant materials. When a foreign government makes conflicting statements, see supra, at 5, or, as here, offers an account in the context of litigation, there may be cause for caution in evaluating the foreign government's submission.
Given the world's many and diverse legal systems, and the range of circumstances in which a foreign government's views may be presented, no single formula or rule will fit all cases in which a foreign government describes its own law. Relevant considerations include the statement's clarity, thoroughness, and support; its context and purpose; the transparency of the foreign legal system; the role and authority of the entity or official offering the statement; and the statement's consistency with the foreign government's past positions.
Judged in this light, the Court of Appeals erred in deeming the Ministry's submission binding, so long as facially reasonable. That unyielding rule is inconsistent with Rule 44.1 (determination of an issue of foreign law “must be treated as a ruling on a question of law”; court may consider “any relevant material or source”) and, tellingly, with this Court's treatment of analogous submissions from States of the United States. If the relevant state law is established by a decision of “the State's highest court,” that decision is “binding on the federal courts.” Wainwright v. Goode, 464 U. S. 78, 84 (1983) (per curiam); see Mullaney v. Wilbur, 421 U. S. 684, 691 (1975). But views of the State's attorney general, while attracting “respectful consideration,” do not garner controlling weight. Arizonans for Official English v. Arizona, 520 U. S. 43, 76–77, n. 30 (1997); see, e.g., Virginia v. American Booksellers Assn., Inc., 484 U. S. 383, 393–396 (1988). Furthermore, because the Court of Appeals riveted its attention on the Ministry's submission, it did not address other evidence, including, for example, China's statement to the WTO that China had “g[i]ve[n] up export administration . . . of vitamin C” at the end of 2001. 810 F. Supp. 2d, at 532 (internal quotation marks omitted).Footnote 5
The Court of Appeals also misperceived this Court's decision in United States v. Pink, 315 U. S. 203 (1942). See 837 F. 3d, at 186–187, 189. Pink, properly comprehended, is not compelling authority for the attribution of controlling weight to the Ministry's brief. We note, first, that Pink was a pre-Rule 44.1 decision. Second, Pink arose in unusual circumstances. Pink was an action brought by the United States to recover assets of the U. S. branch of a Russian insurance company that had been nationalized in 1918, after the Russian revolution. 315 U. S., at 210–211. In 1933, the Soviet Government assigned the nationalized assets located in this country to the United States. Id., at 211–212. The disposition of the case turned on the extraterritorial effect of the nationalization decree—specifically, whether the decree reached assets of the Russian insurance company located in the United States, or was instead limited to property in Russia. Id., at 213–215, 217. To support the position that the decree reached all of the company's assets, the United States obtained an “official declaration of the Commissariat for Justice” of the Russian Socialist Federal Soviet Republic. Id., at 218. The declaration certified that the nationalization decree reached “the funds and property of former insurance companies . . . irrespective of whether [they were] situated within the territorial limits of [Russia] or abroad.” Id., at 220 (internal quotation marks omitted). This Court determined that “the evidence supported [a] finding” that “the Commissariat for Justice ha[d] power to interpret existing Russian law.” Ibid. “That being true,” the Court concluded, the “official declaration [wa]s conclusive so far as the intended extraterritorial effect of the Russian decree [wa]s concerned.” Ibid.
This Court's treatment of the Commissariat's submission as conclusive rested on a document obtained by the United States, through official “diplomatic channels.” Id., at 218. There was no indication that the declaration was inconsistent with the Soviet Union's past statements. Indeed, the Court emphasized that the declaration was consistent with expert evidence in point. See ibid. That the Commissariat's declaration was deemed “conclusive” in the circumstances Pink presented scarcely suggests that all submissions by a foreign government are entitled to the same weight.
The Court of Appeals also reasoned that a foreign government's characterization of its own laws should be afforded “the same respect and treatment that we would expect our government to receive in comparable matters.” 837 F. 3d, at 189. The concern for reciprocity is sound, but it does not warrant the Court of Appeals' judgment. Indeed, the United States, historically, has not argued that foreign courts are bound to accept its characterizations or precluded from considering other relevant sources.Footnote 6
The understanding that a government's expressed view of its own law is ordinarily entitled to substantial but not conclusive weight is also consistent with two international treaties that establish formal mechanisms by which one government may obtain from another an official statement characterizing its laws. Those treaties specify that “[t]he information given in the reply shall not bind the judicial authority from which the request emanated.” European Convention on Information on Foreign Law, Art. 8, June 7, 1968, 720 U. N. T. S. 154; see Inter-American Convention on Proof of and Information on Foreign Law, Art. 6, May 8, 1979, O. A. S. T. S. 1439 U. N. T. S. 111 (similar). Although the United States is not a party to those treaties, they reflect an international practice inconsistent with the Court of Appeals' “binding, if reasonable” resolution.
* * *
Because the Court of Appeals concluded that the District Court was bound to defer to the Ministry's brief, the court did not consider the shortcomings the District Court identified in the Ministry's position or other aspects of “the [D]istrict [C]ourt's careful and thorough treatment of the evidence before it.” 837 F. 3d, at 191, n. 10. The correct interpretation of Chinese law is not before this Court, and we take no position on it. But the materials identified by the District Court were at least relevant to the weight the Ministry's submissions should receive and to the question whether Chinese law required the Chinese sellers' conduct. We therefore vacate the judgment of the Court of Appeals and remand the case for renewed consideration consistent with this opinion.
It is so ordered.
