Principles of Chinese Contract Law

Chinese contract law is built on foundational principles that inform the interpretation, performance, and enforcement of contracts. These principles, codified in Book III of the Civil Code, reflect both the civilian tradition of European contract law and the distinctive characteristics of China’s socialist market economy.

Freedom of Contract

Freedom of contract (hetong ziyou, 合同自由) is the foundational principle of Chinese contract law, though its scope is narrower than in Western systems. Article 4 of the Contract Law and Article 5 of the Civil Code provide that parties have the right to voluntarily enter into contracts and that no entity or individual may unlawfully interfere. This principle encompasses the freedom to choose contracting parties, to determine contract terms, to conclude or not conclude a contract, and to choose the form of contract.

The principle is subject to significant limitations. Mandatory provisions of law — particularly those relating to public order, state planning, and consumer protection — may override contractual freedom. Administrative licensing requirements restrict the freedom to contract in regulated industries. The principle of public interest (gonggong liyi) provides a general limitation on contractual freedom, allowing courts to invalidate contracts that harm social or state interests. The state’s role in economic regulation, including price controls and industry policies, further constrains contractual freedom in practice.

Equality of Parties

The principle of equality (pingdeng yuanze, 平等原则) requires that parties to a contract have equal legal status, regardless of differences in economic power, administrative authority, or social position. Article 4 of the Civil Code provides that all persons have equal legal status in civil activities. This principle is particularly significant in China because of the historical legacy of administrative intervention in economic relations and the continuing involvement of state-owned enterprises in commercial transactions.

The equality principle prohibits government entities from using administrative power to impose contractual terms on private parties. It also prohibits state-owned enterprises from relying on their privileged position to extract unfair advantages from private counterparties. However, the principle’s effectiveness is limited by the practical reality that government entities and state-owned enterprises often wield disproportionate bargaining power. Courts have applied the equality principle to invalidate contracts imposed through administrative pressure, but enforcement remains inconsistent.

Good Faith (Chengxin Yongxin)

The principle of good faith (chengxin yongxin, 诚信信用) is one of the most important general principles of Chinese civil law. Article 7 of the Civil Code provides that parties shall conduct civil activities in good faith and shall not abuse their rights. Article 509 specifically requires parties to perform contractual obligations in good faith.

The good faith principle applies throughout the lifecycle of a contract: it governs pre-contractual negotiations (requiring disclosure of material information and prohibiting fraudulent inducement), contract performance (requiring cooperation and honest dealing), and contract enforcement (prohibiting abuse of rights and forum shopping). The Supreme People’s Court has issued guidance on the application of good faith, treating it as an interpretive principle that may supplement or even override express contractual terms in appropriate cases. The principle has been applied to imply obligations of disclosure, cooperation, and loyalty that are not expressly stated in the contract.

Public Order and Good Customs (Gongxu Liangsu)

The principle of public order and good customs (gongxu liangsu, 公序良俗) serves as a general limitation on contractual freedom. Article 153 of the Civil Code provides that a contract violating mandatory provisions of law or harming public interest is void. The principle allows courts to invalidate contracts that offend fundamental social values, even if they do not violate specific legal prohibitions.

Chinese courts have applied the principle to invalidate contracts involving gambling debts, prostitution, human trafficking, and other activities contrary to socialist core values. The principle has also been applied in commercial contexts to invalidate contracts that circumvent regulatory requirements or harm third-party interests. The scope of public order has expanded in recent years to include socialist core values (shehui zhuyi hexin jiazhiguan), which courts may reference when determining whether a contract violates public order.

Qingquan Heyi (Liability Concurrence)

The principle of liability concurrence (qingquan heyi, 请求权竞合) addresses situations where a party’s conduct simultaneously constitutes a breach of contract and a tort. Article 186 of the Civil Code provides that where a party’s breach of contract harms the other party’s personal or property rights, the injured party may choose to claim either contractual liability or tort liability.

The principle gives the injured party the right to choose the more favorable cause of action. This is significant because contractual and tort claims differ in limitation periods, damage measures, and available remedies. Contractual damages may be limited by foreseeability (Article 584), while tort damages may include moral damages not available in contract. The choice between remedies must be made at the time of filing and cannot be changed after the proceeding has commenced. The qingquan heyi principle reflects the Civil Code’s recognition that the traditional boundaries between contract and tort are not always clear and that injured parties should have access to the most appropriate remedy.

Significance

These principles form the interpretive framework for Chinese contract law. They guide courts in resolving disputes where statutory provisions are ambiguous, supplement the express terms of contracts, and define the limits of party autonomy. The interaction between these principles — particularly the tension between freedom of contract and public order — shapes the distinctive character of Chinese contract law as an instrument of both private ordering and state regulation.
