opinion: Justice Blackmun
  delivered the opinion of the Court.
  We granted certiorari in this case, 460 U. S. 1021 (1983), to decide whether the Supreme Court of Texas correctly ruled that the contacts of a foreign corporation with the State of Texas were sufficient to allow a Texas state court to assert jurisdiction over the corporation in a cause of action not arising out of or related to the corporation’s activities within the State.
  I
  Petitioner Helicopteros Nacionales de Colombia, S. A. (Helicol), is a Colombian corporation with its principal place of business in the city of Bogota in that country. It is engaged in the business of providing helicopter transportation for oil and construction companies in South America. On January 26, 1976, a helicopter owned by Helicol crashed in Peru. Four United States citizens were among those who lost their lives in the accident. Respondents are the survivors and representatives of the four decedents.
  At the time of the crash, respondents’ decedents were employed by Consorcio, a Peruvian consortium, and were working on a pipeline in Peru. Consorcio is the alter ego of a joint venture named Williams-Sedco-Horn (WSH). The venture had its headquarters in Houston, Tex. Consorcio had been formed to enable the venturers to enter into a contract with Petro Peru, the Peruvian state-owned oil company. Consorcio was to construct a pipeline for Petro Peni running from the interior of Peru westward to the Pacific Ocean. Peruvian law forbade construction of the pipeline by any non-Peruvian entity.
  Consorcio/WSH needed helicopters to move personnel, materials, and equipment into and out of the construction area. In 1974, upon request of Consorcio/WSH, the chief executive officer of Helicol, Francisco Restrepo, flew to the United States and conferred in Houston with representatives of the three joint venturers. At that meeting, there was a discussion of prices, availability, working conditions, fuel, supplies, and housing. Restrepo represented that Helicol could have the first helicopter on the job in 15 days. The Consorcio/WSH representatives decided to accept the contract proposed by Restrepo. Helicol began performing before the agreement was formally signed in Peru on November 11, 1974. The contract was written in Spanish on official government stationery and provided that the residence of all the parties would be Lima, Peru. It further stated that controversies arising out of the contract would be submitted to the jurisdiction of Peruvian courts. In addition, it provided that Consorcio/WSH would make payments to Helicol’s account with the Bank of America in New York City. App. 12a.
  Aside from the negotiation session in Houston between Restrepo and the representatives of Consorcio/WSH, Helicol had other contacts with Texas. During the years 1970-1977, it purchased helicopters (approximately 80% of its fleet), spare parts, and accessories for more than $4 million from Bell Helicopter Company in Fort Worth. In that period, Helicol sent prospective pilots to Fort Worth for training and to ferry the aircraft to South America. It also sent management and maintenance personnel to visit Bell Helicopter in Fort Worth during the same period in order to receive “plant familiarization” and for technical consultation. Helicol received into its New York City and Panama City, Fla., bank accounts over $5 million in payments from Consorcio/WSH drawn upon First City National Bank of Houston.
  Beyond the foregoing, there have been no other business contacts between Helicol and the State of Texas. Helicol never has been authorized to do business in Texas and never has had an agent for the service of process within the State. It never has performed helicopter operations in Texas or sold any product that reached Texas, never solicited business in Texas, never signed any contract in Texas, never had any employee based there, and never recruited an employee in Texas. In addition, Helicol never has owned real or personal property in Texas and never has maintained an office or establishment there. Helicol has maintained no records in Texas and has no shareholders in that State. None of the respondents or their decedents were domiciled in Texas, Tr. of Oral Arg. 17,18, but all of the decedents were hired in Houston by Consorcio/WSH to work on the Petro Peru pipeline project.
  Respondents instituted wrongful-death actions in the District Court of Harris County, Tex., against Consorcio/WSH, Bell Helicopter Company, and Helicol. Helicol filed special appearances and moved to dismiss the actions for lack of in personam jurisdiction over it. The motion was denied. After a consolidated jury trial, judgment was entered against Helicol on a jury verdict of $1,141,200 in favor of respondents. App. 174a.
  The Texas Court of Civil Appeals, Houston, First District, reversed the judgment of the District Court, holding that in personam jurisdiction over Helicol was lacking. 616 S. W. 2d 247 (1981). The Supreme Court of Texas, with three justices dissenting, initially affirmed the judgment of the Court of Civil Appeals. App. to Pet. for Cert. 46a-62a. Seven months later, however, on motion for rehearing, the court withdrew its prior opinions and, again with three justices dissenting, reversed the judgment of the intermediate court. 638 S. W. 2d 870 (1982). In ruling that the Texas courts had in personam jurisdiction, the Texas Supreme Court first held that the State’s long-arm statute reaches as far as the Due Process Clause of the Fourteenth Amendment permits. Id., at 872. Thus, the only question remaining for the court to decide was whether it was consistent with the Due Process Clause for Texas courts to assert in personam jurisdiction over Helicol. Ibid.
  II
  The Due Process Clause of the Fourteenth Amendment operates to limit the power of a State to assert in personam jurisdiction over a nonresident defendant. Pennoyer v. Neff, 95 U. S. 714 (1878). Due process requirements are satisfied when in personam jurisdiction is asserted over a nonresident corporate defendant that has “certain minimum contacts with [the forum] such that the maintenance of the suit does not offend ‘traditional notions of fair play and substantial justice.’” International Shoe Co. v. Washington, 326 U. S. 310, 316 (1945), quoting Milliken v. Meyer, 311 U. S. 457, 463 (1940). When a controversy is related to or “arises out of” a defendant’s contacts with the forum, the Court has said that a “relationship among the defendant, the forum, and the litigation” is the essential foundation of in personam jurisdiction. Shaffer v. Heitner, 433 U. S. 186, 204 (1977).
  Even when the cause of action does not arise out of or relate to the foreign corporation’s activities in the forum State, due process is not offended by a State’s subjecting the corporation to its in personam jurisdiction when there are sufficient contacts between the State and the foreign corporation. Perkins v. Benguet Consolidated Mining Co., 342 U. S. 437 (1952); see Keeton v. Hustler Magazine, Inc., 465 U. S. 770, 779-780 (1984). In Perkins, the Court addressed a situation in which state courts had asserted general jurisdiction over a defendant foreign corporation. During the Japanese occupation of the Philippine Islands, the president and general manager of a Philippine mining corporation maintained an office in Ohio from which he conducted activities on behalf of the company. He kept company files and held directors’ meetings in the office, carried on correspondence relating to the business, distributed salary checks drawn on two active Ohio bank accounts, engaged an Ohio bank to act as transfer agent, and supervised policies dealing with the rehabilitation of the corporation’s properties in the Philippines. In short, the foreign corporation, through its president, “ha[d] been carrying on in Ohio a continuous and systematic, but limited, part of its general business,” and the exercise of general jurisdiction over the Philippine corporation by an Ohio court was “reasonable and just.” 342 U. S., at 438, 445.
  All parties to the present case concede that respondents’ claims against Helicol did not “arise out of,” and are not related to, Helicol’s activities within Texas. We thus must explore the nature of Helicol’s contacts with the State of Texas to determine whether they constitute the kind of continuous and systematic general business contacts the Court found to exist in Perkins. We hold that they do not.
  It is undisputed that Helicol does not have a place of business in Texas and never has been licensed to do business in the State. Basically, Helicol’s contacts with Texas consisted of sending its chief executive officer to Houston for a contract-negotiation session; accepting into its New York bank account checks drawn on a Houston bank; purchasing helicopters, equipment, and training services from Bell Helicopter for substantial sums; and sending personnel to Bell’s facilities in Fort Worth for training.
  The one trip to Houston by Helicol’s chief executive officer for the purpose of negotiating the transportation-services contract with Consorcio/WSH cannot be described or regarded as a contact of a “continuous and systematic” nature, as Perkins described it, see also International Shoe Co. v. Washington, 326 U. S., at 320, and thus cannot support an assertion of in personam jurisdiction over Helicol by a Texas court. Similarly, Helicol’s acceptance from Consorcio/WSH of checks drawn on a Texas bank is of negligible significance for purposes of determining whether Helicol had sufficient contacts in Texas. There is no indication that Helicol ever requested that the checks be drawn on a Texas bank or that there was any negotiation between Helicol and Consor-cio/WSH with respect to the location or identity of the bank on which checks would be drawn. Common sense and everyday experience suggest that, absent unusual circumstances, the bank on which a check is drawn is generally of little consequence to the payee and is a matter left to the discretion of the drawer. Such unilateral activity of another party or a third person is not an appropriate consideration when determining whether a defendant has sufficient contacts with a forum State to justify an assertion of jurisdiction. See Kulko v. California Superior Court, 436 U. S. 84, 93 (1978) (arbitrary to subject one parent to suit in any State where other parent chooses to spend time while having custody of child pursuant to separation agreement); Hanson v. Denckla, 357 U. S. 235, 253 (1958) (“The unilateral activity of those who claim some relationship with a nonresident defendant cannot satisfy the requirement of contact with the forum State”); see also Lilly, Jurisdiction Over Domestic and Alien Defendants, 69 Va. L. Rev. 85, 99 (1983).
  The Texas Supreme Court focused on the purchases and the related training trips in finding contacts sufficient to support an assertion of jurisdiction. We do not agree with that assessment, for the Court’s opinion in Rosenberg Bros. & Co. v. Curtis Brown Co., 260 U. S. 516 (1923) (Brandeis, J., for a unanimous tribunal), makes clear that purchases and related trips, standing alone, are not a sufficient basis for a State’s assertion of jurisdiction.
  The defendant in Rosenberg was a small retailer in Tulsa, Okla., who dealt in men’s clothing and furnishings. It never had applied for a license to do business in New York, nor had it at any time authorized suit to be brought against it there. It never had an established place of business in New York and never regularly carried on business in that State. Its only connection with New York was that it purchased from New York wholesalers a large portion of the merchandise sold in its Tulsa store. The purchases sometimes were made by correspondence and sometimes through visits to New York by an officer of the defendant. The Court concluded: “Visits on such business, even if occurring at regular intervals, would not warrant the inference that the corporation was present within the jurisdiction of [New York].” Id., at 518.
  This Court in International Shoe acknowledged and did not repudiate its holding in Rosenberg. See 326 U. S., at 318. In accordance with Rosenberg, we hold that mere purchases, even if occurring at regular intervals, are not enough to warrant a State’s assertion of in personam jurisdiction over a nonresident corporation in a cause of action not related to those purchase transactions. Nor can we conclude that the fact that Helicol sent personnel into Texas for training in connection with the purchase of helicopters and equipment in that State in any way enhanced the nature of Helicol’s contacts with Texas. The training was a part of the package of goods and services purchased by Helicol from Bell Helicopter. The brief presence of Helicol employees in Texas for the purpose of attending the training sessions is no more a significant contact than were the trips to New York made by the buyer for the retail store in Rosenberg. See also Kulko v. California Superior Court, 436 U. S., at 93 (basing California jurisdiction on 3-day and 1-day stopovers in that State “would make a mockery of” due process limitations on assertion of personal jurisdiction).
  III
  We hold that Helicol’s contacts with the State of Texas were insufficient to satisfy the requirements of the Due Process Clause of the Fourteenth Amendment. Accordingly, we reverse the judgment of the Supreme Court of Texas.
  It is so ordered.
  The participants in the joint venture were Williams International Sudamericana, Ltd., a Delaware corporation; Sedeo Construction Corporation, a Texas corporation; and Horn International, Inc., a Texas corporation.
  Throughout the record in this case the entity is referred to both as Consorcio and as WSH. We refer to it hereinafter as Consorcio/WSH.
  Respondents acknowledge that the contract was executed in Peru and not in the United States. Tr. of Oral Arg. 22-23. See App. 79a; Brief for Respondents 3.
  The Colombian national airline, Aerovías Nacionales de Colombia, owns approximately 94% of Helicol’s capital stock. The remainder is held by Aerovías Corporación de Viajes and four South American individuals. See Brief for Petitioner 2, n. 2.
  Respondents’ lack of residential or other contacts with Texas of itself does not defeat otherwise proper jurisdiction. Keeton v. Hustler Magazine, Inc., 465 U. S. 770, 780 (1984); Calder v. Jones, 465 U. S. 783, 788 (1984). We mention respondents’ lack of contacts merely to show that nothing in the nature of the relationship between respondents and Helicol could possibly enhance Helicol’s contacts with Texas. The harm suffered by respondents did not occur in Texas. Nor is it alleged that any negligence on the part of Helicol took place in Texas.
  Defendants Consorcio/WSH and Bell Helicopter Company were granted directed verdicts with respect to respondents’ claims against them. Bell Helicopter was granted a directed verdict on Helicol’s cross-claim against it. App. 167a. Consorcio/WSH, as cross-plaintiff in a claim against Helicol, obtained a judgment in the amount of $70,000. Id., at 174a.
  The State’s long-arm statute is Tex. Rev. Civ. Stat. Ann., Art. 2031b (Vernon 1964 and Supp. 1982-1983). It reads in relevant part:
  “Sec. 3. Any foreign corporation . . . that engages in business in this State, irrespective of any Statute or law respecting designation or maintenance of resident agents, and does not maintain a place of regular business in this State or a designated agent upon whom service may be made upon causes of action arising out of such business done in this State, the act or acts of engaging in such business within this State shall be deemed equivalent to an appointment by such foreign corporation ... of the Secretary of State of Texas as agent upon whom service of process may be made in any action, suit or proceedings arising out of such business done in this State, wherein such corporation ... is a party or is to be made a party.
  “Sec. 4. For the purpose of this Act, and without including other acts that may constitute doing business, any foreign corporation . . . shall be deemed doing business in this State by entering into contract by mail or otherwise with a resident of Texas to be performed in whole or in part by either party in this State, or the committing of any tort in whole or in part in this State. The act of recruiting Texas residents, directly or through an intermediary located in Texas, for employment inside or outside of Texas shall be deemed doing business in this State.”
  The last sentence of §4 was added by 1979 Tex. Gen. Laws, ch. 245, § 1, and became effective August 27, 1979.
  The Supreme Court of Texas in its principal opinion relied upon rulings in U-Anchor Advertising, Inc. v. Burt, 553 S. W. 2d 760 (Tex. 1977); Hoppenfeld v. Crook, 498 S. W. 2d 52 (Tex. Civ. App. 1973); and O’Brien v. Lanpar Co., 399 S. W. 2d 340 (Tex. 1966). It is not within our province, of course, to determine whether the Texas Supreme Court correctly interpreted the State’s long-arm statute. We therefore accept that court’s holding that the limits of the Texas statute are coextensive with those of the Due Process Clause.
  It has been said that when a State exercises personal jurisdiction over a defendant in a suit arising out of or related to the defendant’s contacts with the forum, the State is exercising “specific jurisdiction” over the defendant. See Von Mehren & Trautman, Jurisdiction to Adjudicate: A Suggested Analysis, 79 Harv. L. Rev. 1121, 1144-1164 (1966).
  When a State exercises personal jurisdiction over a defendant in a suit not arising out of or related to the defendant’s contacts with the forum, the State has been said to be exercising “general jurisdiction” over the defendant. See Brilmayer, How Contacts Count: Due Process Limitations on State Court Jurisdiction, 1980 S. Ct. Rev. 77, 80-81; Von Mehren & Trautman, 79 Harv. L. Rev., at 1136-1144; Calder v. Jones, 465 U. S., at 786.
  See Brief for Respondents 14; Tr. of Oral Arg. 26-27, 30-31. Because the parties have not argued any relationship between the cause of action and Helicol’s contacts with the State of Texas, we, contrary to the dissent’s implication, post, at 419-420, assert no “view” with respect to that issue.
  The dissent suggests that we have erred in drawing no distinction between controversies that “relate to” a defendant’s contacts with a forum and those that “arise out of” such contacts. Post, at 420. This criticism is somewhat puzzling, for the dissent goes on to urge that, for purposes of determining the constitutional validity of an assertion of specific jurisdiction, there really should be no distinction between the two. Post, at 427-428.
  We do not address the validity or consequences of such a distinction because the issue has not been presented in this case. Respondents have made no argument that their cause of action either arose out of or is related to Helicol’s contacts with the State of Texas. Absent any briefing on the issue, we decline to reach the questions (1) whether the terms “arising out of” and “related to” describe different connections between a cause of action and a defendant’s contacts with a forum, and (2) what sort of tie between a cause of action and a defendant’s contacts with a forum is necessary to a determination that either connection exists. Nor do we reach the question whether, if the two types of relationship differ, a forum’s exercise of personal jurisdiction in a situation where the cause of action “relates to,” but does not “arise out of,” the defendant’s contacts with the forum should be analyzed as an assertion of specific jurisdiction.
  For example, if the financial health and continued ability of the bank to honor the draft are questionable, the payee might request that the check be drawn on an account at some other institution.
  This Court in International Shoe cited Rosenberg for the proposition that “the commission of some single or occasional acts of the corporate agent in a state sufficient to impose an obligation or liability on the corporation has not been thought to confer upon the state authority to enforce it.” 326 U. S., at 318. Arguably, therefore, Rosenberg also stands for the proposition that mere purchases are not a sufficient basis for either general or specific jurisdiction. Because the case before us is one in which there has been an assertion of general jurisdiction over a foreign defendant, we need not decide the continuing validity of Rosenberg with respect to an assertion of specific jurisdiction, i. e., where the cause of action arises out of or relates to the purchases by the defendant in the forum State.
  As an alternative to traditional minimum-contacts analysis, respondents suggest that the Court hold that the State of Texas had personal jurisdiction over Helicol under a doctrine of “jurisdiction by necessity.” See Shaffer v. Heitner, 433 U. S. 186, 211, n. 37 (1977). We conclude, however, that respondents failed to carry their burden of showing that all three defendants could not be sued together in a single forum. It is not clear from the record, for example, whether suit could have been brought against all three defendants in either Colombia or Peru. We decline to consider adoption of a doctrine of jurisdiction by necessity — a potentially far-reaching modification of existing law — in the absence of a more complete record.
