The appellants were among the plaintiffs in the district court and are employees of foreign companies that sell goods to WalMart Stores, Inc. (“Wal-Mart”). They brought claims against Wal-Mart based on the working conditions in each of their
I
Plaintiffs are employees of Wal-Mart’s foreign suppliers in countries including China, Bangladesh, Indonesia, Swaziland, and Nicaragua. Plaintiffs allege the following relevant facts, which we take as true for purposes of this appeal:
In 1992, Wal-Mart developed a code of conduct for its suppliers, entitled “Standards for Suppliers” (“Standards”). These Standards were incorporated into its supply contracts with foreign suppliers. The Standards require foreign suppliers to adhere to local laws and local industry standards regarding working conditions like pay, hours, forced labor, child labor, and discrimination. The Standards also include a paragraph entitled “RIGHT OF INSPECTION”:
To further assure proper implementation of and compliance with the standards set forth herein, Wal-Mart or a third party designated by Wal-Mart will undertake affirmative measures, such as on-site inspection of production facilities, to implement and monitor said standards. Any supplier which fails or refuses to comply with these standards or does not allow inspection of production facilities is subject to immediate cancellation of any and all outstanding orders, refuse [sic] or return [sic] any shipment, and otherwise cease doing business [sic] with Wal-Mart.
Thus, each supplier must acknowledge that its failure to comply with the Standards could result in cancellation of orders and termination of its business relationship with Wal-Mart.
Wal-Mart represents to the public that it improves the lives of its suppliers’ employees and that it does not condone any violation of the Standards. However, Plaintiffs allege that Wal-Mart does not adequately-monitor its suppliers and that Wal-Mart knows its suppliers often violate the Standards. Specifically, Plaintiffs claim that in 2004, only eight percent of audits were unannounced, and that workers are often coached on how to respond to auditors. Additionally, Plaintiffs allege that Wal-Mart’s inspectors were pressured to produce positive reports of factories that were not in compliance with the Standards. Finally, Plaintiffs allege that the short deadlines and low prices in WalMart’s supply contracts force suppliers to violate the Standards in order to satisfy the terms of the contracts.
Plaintiffs filed a class action lawsuit in California Superior Court in 2005 and Wal-Mart removed the case to federal court based on diversity of citizenship. Plaintiffs then filed an amended complaint in federal court, which is the complaint relevant here. Wal-Mart filed a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim. The district court granted the motion in a written order, and judgment was entered on March 27, 2008. 2 Plaintiffs timely appealed.

III
Plaintiffs present four distinct legal theories, all of which aim to establish that the Standards and California common law provide substantive obligations that can be enforced by the foreign workers against Wal-Mart: (1) Plaintiffs are third-party beneficiaries of the Standards contained in Wal-Mart’s supply contracts; 3 (2) WalMart is Plaintiffs’ joint employer; (3) WalMart negligently breached a duty to monitor the suppliers and protect Plaintiffs from the suppliers’ working conditions; (4) Wal-Mart was unjustly enriched by Plaintiffs’ mistreatment. Applying California law, we address each claim in turn.
A
We first address Plaintiffs’ third-party beneficiary theory. The common law in California and elsewhere establishes that, as recited in the applicable Restatement (Second) of Contracts: “A promise in a contract creates a duty in the promisor to any intended beneficiary to perform the promise, and the intended beneficiary may enforce the duty.” Restatement (Second) of Contracts § 304 (1981). However, the Restatement also explains that a beneficiary is only “an intended beneficiary if recognition of a right to performance in the beneficiary is appropriate to effectuate the intention of the parties.... ” Restatement (Second) of Contracts § 302(1). Contract interpretation is a question of law that we review
de novo. See Milenbach v. Comm’r of Internal Revenue,
Plaintiffs argue that Wal-Mart promised the suppliers that it would monitor the suppliers’ compliance with the Standards, and that Plaintiffs are third-party beneficiaries of that promise to monitor. Plaintiffs rely on this language in the Standards: “Wal-Mart will undertake affirmative measures, such as on-site inspection of production facilities, to implement and monitor said standards.” We agree with the district court that this language does not create a duty on the part of WalMart to monitor the suppliers, and does not provide Plaintiffs a right of action against Wal-Mart as third-party beneficiaries.
The language and structure of the agreement show that Wal-Mart reserved
Plaintiffs alternatively argue that they are third-party beneficiaries of the suppliers’ promises to maintain certain working conditions, and that Plaintiffs may therefore sue Wal-Mart. This theory fails because Wal-Mart was the promisee vis-a-vis the suppliers’ promises to follow the Standards, and Plaintiffs have not plausibly alleged a contractual duty on the part of Wal-Mart that would extend to Plaintiffs.
See Martinez v. Socoma Cos.,
Plaintiffs’ allegations are insufficient to support the conclusion that Wal-Mart and the suppliers intended for Plaintiffs to have a right of performance against WalMart under the supply contracts. See Restatement (Second) of Contracts § 302(1). We therefore conclude that Plaintiffs have not stated a claim against Wal-Mart as third-party beneficiaries of any contractual duty owed by Wal-Mart, and we affirm the district court’s dismissal of the third-party beneficiary contract claim.
B
We next address Plaintiffs’ theory that Wal-Mart was Plaintiffs’ joint employer, such that they can “sue Wal-Mart directly for any breach of contract or violation of labor laws.” We conclude, to the contrary, that Wal-Mart cannot be considered Plaintiffs’ employer on the facts alleged.
The key factor to consider in analyzing whether an entity is an employer is “the right to control and direct the activities of the person rendering service, or the manner and method in which the work is performed.”
Serv. Employees Inti Union v. County of L.A.,
Plaintiffs also allege that Wal-Mart exercised control over their employment through Wal-Mart’s promise to monitor the suppliers and Wal-Mart’s system for monitoring. However, we have already concluded that Wal-Mart undertook no duty to monitor the suppliers and the monitoring and inspections by Wal-Mart were performed to determine whether suppliers were meeting their contractual obligations, not to direct the daily work activity of the suppliers’ employees.
Plaintiffs have provided no persuasive support for finding a common law employment relationship between a purchaser and its suppliers’ employees on the facts of this case. 5 We conclude that the joint employer theory should here be rejected, and we hold that Wal-Mart is not Plaintiffs’ employer.
C
We next address Plaintiffs’ negligence claims, which Plaintiffs bring under four distinct theories: third-party beneficiary negligence, negligent retention of control, negligent undertaking, and common law negligence. Whichever theory is invoked, however, we conclude that WalMart did not owe Plaintiffs a common-law duty to monitor Wal-Mart’s suppliers or to prevent the alleged intentional mistreatment of Plaintiffs by the suppliers. Without such a duty, Plaintiffs’ negligence theories do not state a claim.
See Paz v. State,
Plaintiffs’ “third-party beneficiary” negligence theory relies on the assumption that Wal-Mart owes Plaintiffs a duty under Wal-Mart’s supply contracts. Because we have already determined that no legal obligation flows from Wal-Mart to Plaintiffs under Wal-Mart’s supply contracts, Plaintiffs do not state a claim for third-party beneficiary negligence.
In order to state a claim for “negligent retention of control and supervision,” Plaintiffs must allege facts that, if proven, would show that Wal-Mart exercised significant control over Plaintiffs and that “exercise of retained control
affirmatively contributed
to the employee’s injuries.”
Hooker v. Dep’t of Transp.,
Plaintiffs’ “negligent undertaking” theory relies on the assumption that Wal-Mart undertook to protect Plaintiffs, and therefore Wal-Mart had to exercise reasonable care in monitoring the suppliers.
See Delgado v. Trax Bar & Grill,
Plaintiffs’ “common law negligence” claim provides no additional ground for finding a duty on the part of Wal-Mart. Wal-Mart had no duty to monitor the suppliers or to protect Plaintiffs from the intentional acts the suppliers allegedly committed. Thus, Plaintiffs’ theories sounding in negligence do not state a claim.
See Paz,
D
We turn finally to Plaintiffs’ claim of unjust enrichment. Plaintiffs allege that Wal-Mart was unjustly enriched at Plaintiffs’ expense by profiting from relationships with suppliers that Wal-Mart knew were engaged in substandard labor practices. Unjust enrichment is commonly understood as a theory upon which the remedy of restitution may be granted.
See
1 George E. Palmer, Law of Restitution § 1.1 (1st ed. 1978 & Supp. 2009); Restatement of Restitution § 1 (1937) (“A person who has been unjustly enriched at the expense of another is required to make restitution to the other.”). California’s approach to unjust enrichment is consistent with this general understanding: “The fact that one person benefits another is not, by itself, sufficient to require restitution. The person receiving the benefit is required to make restitution only if the circumstances are such that, as between the two individuals, it is
unjust
for the person to retain it.”
First Nationwide Sav. v. Perry,
IV
In sum, we conclude that Plaintiffs have not stated a claim against Wal-Mart. 6 Wal-Mart had no legal duty under the Standards or common law negligence principles to monitor its suppliers or to protect Plaintiffs from the suppliers’ alleged substandard labor practices. Wal-Mart is not Plaintiffs’ employer, and the relationship between Wal-Mart and Plaintiffs is too attenuated to support restitution under an unjust enrichment theory.
AFFIRMED.
Notes
. The complaint also included claims by California plaintiffs, who were employees of WalMart’s competitors. However, this appeal is brought only by the foreign plaintiffs.
. The district court granted Wal-Mart's motion to dismiss on April 2, 2007, but granted Plaintiffs 21 days' leave to amend. Instead of amending, Plaintiffs appealed; however, because no final judgment had been issued the
. The parties disputed before the district court whether California or Arkansas law applies to Plaintiffs' third-party beneficiary contract claim. However, we need not now address that issue because the parties agree that both states apply the Restatement (Second)’s approach to third-party beneficiaries.
. The Restatement does suggest that a promisee may be liable to a third-party beneficiary when "the performance of the promise will satisfy an obligation of the promisee to pay money to the beneficiary.” Restatement (Second) of Contracts § 302(l)(a). The third-party creditor in such a case is commonly known as a "creditor beneficiary.” Restatement (Second) of Contracts § 302, cmt. d. However, Plaintiffs have alleged no prior obligation by Wal-Mart that could support finding a contractual duty owed to Plaintiffs by WalMart, and so the suppliers’ employees cannot be considered to be creditor beneficiaries.
. The cases cited by Plaintiffs regarding employment relationships are inapposite. Some of Plaintiffs’ authorities rely on specific statutory and regulatory schemes, like the Fair Labor Standards Act ("FLSA”), 29 U.S.C. §§ 201-219, that use a definition of "employer” inapplicable to this context.
See, e.g., Bureerong v. Uvawas,
. Because we have determined that Plaintiffs did not state a claim under state law, we need not address Wal-Mart's additional contentions that United States domestic law does not apply and that foreign affairs preemption bars application of state law.
