delivered the opinion of the Court.
Section 106 of Pub. L. 92-129, 85 Stat. 355, note following 5 U. S. C. §7201 (1976 ed., Supp. IV), prohibits employment discrimination against United States citizens on military bases overseas unless permitted by “treaty.” The question in this case is whether “treaty” includes executive agreements concluded by the President with the host country, or whether the term is limited to those international agreements entered into by the President with the advice and consent of the Senate pursuant to Art. II, § 2, cl. 2, of the United States Constitution. This issue is solely one of statutory interpretation.
I
In 1944, Congress authorized the President, “by such means as he finds appropriate,” to acquire, after negotiation with the President of the Philippines, military bases “he may deem necessary for the mutual protection of the Philippine Islands and of the United States.” 58 Stat. 626, 22 U. S. C. § 1392. Pursuant to this statute, the United States and the
In 1971, Congress enacted § 106 of Pub. L. 92-129, the employment discrimination statute at issue in this case. 3 At the time §106 was enacted, 12 agreements in addition to the BLA were in effect providing for preferential hiring of local nationals on United States military bases overseas. Since § 106 was enacted, four more such agreements have been concluded. 4 None of these agreements were submitted to the Senate for its advice and consent pursuant to Art. II, § 2, cl. 2, of the Constitution.
II
Simply because the question presented is entirely one of statutory construction does not mean that the question necessarily admits of an easy answer. Chief Justice Marshall long ago observed that “[wjhere the mind labours to discover the design of the legislature, it seizes every thing from which aid can be derived .. . .”
United States
v.
Fisher,
“Generalities about statutory construction help us little. They are not rules of law but merely axioms of experience. They do not solve the special difficulties in construing a particular statute. The variables render every problem of statutory construction unique.” United States v. Universal Corp.,344 U. S. 218 , 221 (1952) (citations omitted).
We naturally begin with the language of § 106, which provides in relevant part as follows:
“Unless prohibited by treaty, no person shall be discriminated against by the Department of Defense or by any officer or employee thereof, in the employment of civilian personnel at any facility or installation operated by the Department of Defense in any foreign country because such person is a citizen of the United States or is a dependent of a member of the Armed Forces of the United States.” 85 Stat. 355, note following 5 U. S. C. § 7201 (1976 ed., Supp. IV) (emphasis added).
The statute is awkwardly worded in the form of a double negative, and we agree with the Court of Appeals that “[r]e-placing the phrase ‘[ujnless prohibited by’ with either the words ‘unless permitted by’ or ‘unless provided by’ would convey more precisely the meaning of the statute, but we do not think that this awkward phrasing bears on congressional intent in selecting the word ‘treaty.’” 206 U. S. App. D. C., at 153, n. 21,
The word “treaty” has more than one meaning. Under principles of international law, the word ordinarily refers to an international agreement concluded between sovereigns, regardless of the manner in which the agreement is brought into force. 206 U. S. App. D. C., at 151,
Congress has not been consistent in distinguishing between Art. II treaties and other forms of international agreements. For example, in the Case Act, 1 U. S. C. § 112b(a) (1976 ed., Supp. IV), Congress required the Secretary of State to “transmit to the Congress the text of any international agreement, . . . other than a treaty, to which the United States is a party” no later than 60 days after “such agreement has entered into force.”
7
Similarly, Congress has explicitly referred to Art. II treaties in the Fishery Conservation and Management Act of 1976, 16 U. S. C. § 1801
et seq.
(1976 ed. and Supp. IV),
8
and the Arms Control and Disarmament Act, 22 U. S. C. § 2551
et seq.
(1976 ed. and Supp. IV).

On the other hand, Congress has used “treaty” to re
The fact that Congress has imparted no precise meaning to the word “treaty” as that term is used in its various legislative Acts was recognized by this Court in
B. Altman & Co.
v.
United States,
The statute involved in the

case in no way affected the foreign policy of the United States, since it dealt only with the jurisdiction of this Court. In the case of a statute such as § 106, that does touch upon the United States’ foreign policy, there is even more reason to construe Congress’ use of “treaty” to include international agreements as well as Art. II treaties. At the time §106 was enacted, 13 executive agreements provided for preferential hiring of local nationals.
Supra,
at 27. Thus, if Congress intended to limit the “treaty exception” in § 106 to Art. II treaties, it must have intended to repudiate these executive agreements that affect the hiring practices of the United States only at its military bases overseas. One would expect that Congress would be aware
It has been a maxim of statutory construction since the decision in
Murray
v.
The Charming Betsy,
At the time § 106 was enacted, there were in force 12 agreements in addition to the BLA providing for preferential hiring of local nationals on United States military bases overseas. Since the time of the enactment of § 106, four more such agreements have been concluded, and none of these were submitted to the Senate for its advice and consent. Supra, at 27. We think that some affirmative expression of congressional intent to abrogate the United States’ international obligations is required in order to construe the word “treaty” in § 106 as meaning only Art. II treaties. We therefore turn to what legislative history is available in order to ascertain whether such an intent may fairly be attributed to Congress.
The legislative history seems to us to indicate that Congress was principally concerned with the financial hardship to
“The purpose of [§ 106] is to correct a situation which exists at some foreign bases, primarily in Europe, where discrimination in favor of local nationals and against American dependents in employment has contributed to conditions of hardship for families of American enlisted men whose dependents are effectively prevented from obtaining employment.” H. R. Conf. Rep. No. 92-433, p. 31 (1971).
The Conference Report, however, is entirely silent as to the scope of the “treaty” exception. Similarly, there is no mention of the 13 agreements that provided for preferential hiring of local nationals. Thus, the Conference Report provides no support whatsoever for the conclusion that Congress intended in some way to limit the President’s use of international agreements that may discriminate against American citizens who seek employment at United States military bases overseas.
On the contrary, the brief congressional debates on this provision indicate that Congress was not concerned with limiting the authority of the President to enter into executive agreements with the host country, but with the ad hoc deci-sionmaking of military commanders overseas. In early 1971, Brig. Gen. Charles H. Phipps, Commanding General of the European Exchange System, issued a memorandum encouraging the recruitment and hiring of local nationals instead of United States citizens at the system’s stores. The hiring of local nationals, General Phipps reasoned, would result in lower wage costs and turnover rates. 10 Senator Schweiker, a sponsor of § 106, complained of General Phipps’ policy. 11
The Court of Appeals relied heavily on a statement by Senator Hughes, a sponsor of § 106, that dependents of enlisted personnel “are denied the opportunity to work on overseas bases, by agreement with the countries in which they are located, and are forced to live in poverty.” 117 Cong. Rec. 16126 (1971). Taken out of context, this remark is certainly supportive of respondents’ position. In context, however, it is not altogether clear to which “agreements” Sena
“On my inquiry of the Defense Department, it was my understanding that there was an agreement, through the NATO organization, that those young wives, because they were there on tourists visas, could not get a work permit under any circumstances.” Ibid.
As we indicated above, the NATO agreements do not contain any provision for preferential hiring of local nationals. Supra, at 34. Senator Hughes could well have been referring to agreements that in effect precluded dependents from working in the local economy. Be that as it may, it suffices to say that one isolated remark by a single Senator, ambiguous in meaning when examined in context, is insufficient to establish the kind of affirmative congressional expression necessary to evidence an intent to abrogate provisions in 13 international agreements. 15
Finally, respondents rely on postenactment legislative history that “firmly reiterate[s] the Congressional policy against preferential hiring of local nationals.” Brief for Respondents 23. In particular, respondents offer two examples of congressional Committees urging the Department of Defense to renegotiate those agreements containing local-national preferential hiring provisions.

statements of a congressional Committee are not entitled to much weight.

v.
GTE Sylvania, Inc.,
While the question is not free from doubt, we conclude that the “treaty” exception contained in § 106 extends to executive agreements as well as to Art. II treaties. The judgment of the Court of Appeals is reversed, and the case is remanded for proceedings consistent with this opinion. 18
It is so ordered.
Notes
This agreement has been amended periodically, most recently on January 7, 1979. [1978-1979] 30 U. S. T. 863, T. I. A. S. No. 9224.
In relevant part, Article I of the BLA provides:
“1. Preferential Employment. — The United States Armed Forces in the Philippines shall fill the needs for civilian employment by employing Filipino citizens, except when the needed skills are found, in consultation with the Philippine Department of Labor, not to be locally available, or when otherwise necessary for reasons of security or special management needs, in which cases United States nationals may be employed. . . .”
Section 106 provides in pertinent part:
“Unless prohibited by treaty, no person shall be discriminated against by the Department of Defense or by any officer or employee thereof, in the employment of civilian personnel at any facility or installation operated by the Department of Defense in any foreign country because such person is a citizen of the United States or is a dependent of a member of the Armed Forces of the United States.” 85 Stat. 355, note following 5 U. S. C. § 7201 (1976 ed., Supp. IV) (emphasis added).

Draft No. 1, Apr. 1, 1980) (“[I]nternational law does not distinguish between agreements designated as ‘treaties’ and other agreements”).
We have recognized, however, that the President may enter into certain binding agreements with foreign nations without complying with the formalities required by the Treaty Clause of the Constitution, even when the agreement compromises commercial claims between United States citizens and a foreign power. See,
e. g., Dames & Moore
v.
Regan,
In this context, it is entirely logical that Congress should distinguish between Art. II treaties and other international agreements. Submission of Art. II treaties to the Senate for ratification is already required by the Constitution.
Congress defined “treaty” to mean “any international fishery agreement which is a treaty within the meaning of section 2 of article II of the Constitution.” 16 U. S. C. § 1802(23).
“[N]o action shall be taken under this chapter or any other law that will obligate the United States to disarm or to reduce or to limit the Armed Forces or armaments of the United States, except pursuant to the treaty making power of the President under the Constitution or unless authorized by further affirmative legislation by the Congress of the United States.” 22 U. S. C. § 2573.
See 117 Cong. Rec. 14395 (1971) (remarks of Sen. Schweiker).
“I have never heard of anything so ridiculous in my life. We actually send our GI’s to Europe at poverty wages. We do not pay to send the wives there. They have to beg or borrow that money. They get over
At another point, Senator Schweiker commented: “Here is an American general saying that when the GI’s go to their canteen or service post exchange and spend their money, they do not even have the right to have their wives working there because we should give those jobs to German nationals.” Id., at 16128.

This NATO agreement is an Art. II treaty.
The contemporaneous remarks of a sponsor of legislation are certainly not controlling in analyzing legislative history.

See H. R. Rep. No. 95-68, p. 25 (1977); H. R. Conf. Rep. No. 97-410, p. 54 (1981).
Although we do not ascribe it much weight, we note that a Conference Committee recently deleted a provision that would have prohibited the hiring of foreign nationals at military bases overseas when qualified United States citizens are available. Ibid. In urging this provision’s deletion, Senator Percy explained that the provision would place the United States in violation of its obligations, inter alia, under the BLA with the Philippines. 127 Cong. Rec. S14110 (Nov. 30, 1981). He argued:
“Some host nations might view enactment of 777 as a material breach of our agreements, thus entitling them to open negotiations on terminating, redefining or further restricting U. S. basing and use rights. Nations could, for example, retaliate by suspending or reducing our current rights to engage in routine military operations such as aircraft transits.” Ibid.
In view of its construction of § 106, the Court of Appeals found it unnecessary to determine whether the BLA in the instant case violated Title VII of the Civil Rights Act of 1964, 42 U. S. C. § 2000e
et seq.
(1976 ed. and Supp. IV).
