Which Law Governs Your China Supply Contract?

The governing-law clause is the most ignored line in cross-border supply contracts. Buyers negotiate price, specifications and delivery dates hard — then leave the question of which legal system referees the whole deal to chance, or to whatever the supplier's PI happens to say. That is a mistake with a specific cost, and it is discoverable in an afternoon. This article explains how Chinese law treats the governing-law choice in China-related contracts, the trap that makes foreign-law choices fail in Chinese courts, and the law-plus-forum packages that actually work.

1. Silence Is Not Neutrality

The foundational point: your contract is governed by something, right now, even if nothing in it says so. The relevant framework is the PRC Law on the Application of Laws to Foreign-Related Civil Relations (2010). Its Article 41 lets the parties choose the law governing their contract. But where the parties make no choice, the court applies the law of the country with the closest connection to the transaction — and for goods manufactured and delivered from China by a Chinese supplier, that means Chinese law, almost always.

So the real difference between a silent contract and one that names Chinese law is smaller than buyers assume. In both cases, Chinese law governs. What the silent contract loses is everything around the label: you never examined what Chinese law would do to your deposit, your quality claims or your termination rights; you never engaged with the treaty sitting on top of it; and you left the drafting to the party that did.

The one honest use of silence is ignorance by choice. Nobody should take it.

2. You Can Choose Your Law — If You Can Prove It

Article 41 does let you pick your own law — French law, New York law, the law of your home jurisdiction. Many foreign buyers draft exactly that clause and feel protected. Then comes Article 10 of the same statute, and the feeling dissolves: the party relying on foreign law in a Chinese court must provide it. The court may assist in obtaining the content of foreign law, and there are proper channels for doing so — but if the party who chose the foreign law cannot prove its content to the court's satisfaction, the court falls back on Chinese law.

Read that twice, because it rewrites the clause's meaning: choosing French law in a Chinese court is a promise to fund expert evidence about your own legal system, with a fallback that hands the case to Chinese law anyway. Foreign-law proof in Chinese litigation is real work — expert reports, sometimes sworn translations, sometimes court-directed methods — and it fails more often than the buyers who drafted the clause ever expected. You spent a clause, paid for the proof, and got the default.

This is the single most useful sentence in this article: a foreign governing-law choice in a Chinese court proceeding is not protection; it is a project. Decide consciously whether that project is worth running for your deal — or pick a forum where the choice actually works (Section 5).

3. Mandatory Rules You Cannot Contract Around

Two provisions of the same statute cap the whole exercise. Article 4 provides that China's mandatory provisions apply regardless of the chosen law; Article 5 preserves the public-policy override. Party autonomy is broad — but it stops at the floor.

And when a dispute actually lands in China — which is where a Chinese supplier's assets are — a whole web of Chinese-specific rules applies regardless of what your clause says. Examples from the PRC Civil Code:

• Deposit rules. Articles 586 and 587 govern the classic Chinese deposit (定金): a deposit exceeding 20% of the contract value loses deposit effect beyond that cap; a breaching buyer loses the deposit; a breaching deposit-taker returns it doubled. These mechanics shape settlement leverage in every payment dispute, whatever your clause says about "deposits" and "refunds."
• Quality-notice rules. Article 621's inspection-period and two-year outside-limit regime conditions quality claims before the merits are even reached.
• Judgment-enforcement realities. A court judgment against a Chinese supplier bites Chinese assets. A foreign judgment in your favor still needs recognition in China before it can touch a bank account in Shenzhen — and recognition is not guaranteed. What enforcement actually involves.

The conclusion is not that governing-law clauses are useless. It is that they must be drafted knowing where the case will actually be fought. A foreign-law clause that cannot be proven, enforced in a forum whose mandatory rules apply anyway, protects nothing — it only adds a layer of complexity to a claim you will someday need to be simple.

4. The CISG Interaction

Choosing Chinese law in a China supply contract usually drags the CISG in with it. China is a contracting state, and Chinese courts treat the treaty as part of the applicable law between parties from contracting states — so your elegant "Chinese law" clause arrives with a 1980 Vienna treaty attached, setting conformity standards, notice deadlines and interest rules you may not have bargained for.

If you want Chinese law without the treaty, exclusion must be express — the clause must say the Convention's name. If you want the treaty, keep it on purpose and know what it does to your notice deadlines. The full mechanics, with model clauses: the CISG and China contracts.

5. Arbitration Changes the Map

Every problem in Sections 2–3 has one structural answer: arbitration. Three reasons traders on China deals so often end up choosing CIETAC, HKIAC or another institution:

• The law you choose is actually applied. Tribunals are used to working with foreign law; parties prove it within the process, without the courtroom fallback problem of Article 10. Your choice becomes real instead of aspirational.
• The award travels. A Chinese-seated or Hong Kong-seated award is enforceable across the many countries that recognize foreign arbitral awards — while a Chinese judgment is primarily a tool against assets in China, and a foreign judgment needs recognition before it can touch anything in China. On the enforcement asymmetry: enforcing judgments against Chinese suppliers.
• One instance, confidential, final. No appeal marathon, no public docket — features that matter more in ongoing supplier relationships than buyers expect.

The full trade-off analysis — institutions, seats, costs, language: arbitration clauses for China deals.

6. Matching the Package to Your Priority

Governing law is never chosen alone — it comes packaged with forum, language and service of process. Match the package to what you actually need the contract to do:

Your priority	Governing law	Forum	Language & service	Why
Quality claims must bite against assets in China	Chinese law, CISG excluded or kept by design	Chinese court or CIETAC (China seat)	Bilingual contract; Chinese-language evidence; process straightforward	The forum that holds the supplier's assets applies Chinese law naturally — no foreign-law proof project
My home law should actually govern	The law you choose	Arbitration (HKIAC, SIAC, CIETAC)	English; arbitral rules handle service and evidence	Arbitration removes the Article 10 proof-fallback and makes the choice real
Speed and settlement leverage	Chinese law	Chinese court, preservation-ready	Bilingual contract; lawyer handles filings	A bank-account freeze moves negotiations faster than any clause
Cost control on smaller deals	Chinese law	Chinese court, simplified or small-claims track	Bilingual; standardized evidence formats	Statutory fee reductions and shorter procedure favor compact, documented claims

Notice what appears in every row: a bilingual contract. The governing-law clause is only as good as the document the court or tribunal will actually read — the bilingual drafting question here.

7. A Model Clause, With Commentary

For the most common buyer profile — foreign buyer, Chinese supplier, assets in China, quality exposure real — the package I most often recommend:

This Agreement shall be governed by and construed in accordance with the laws of the People's Republic of China, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG). Any dispute arising out of or in connection with this Agreement shall be referred to and finally resolved by arbitration administered by the China International Economic and Trade Arbitration Commission (CIETAC) under its rules in force at the date of submission of the arbitration application. The seat of arbitration shall be Shanghai. The language of the arbitration shall be English, with Chinese translations of all evidence submitted in English.

Why each piece:

• Chinese law. Not nostalgia — arithmetic. The enforcement forum applies it anyway, the mandatory rules were never leaving, and naming it removes the foreign-law proof project entirely.
• CISG excluded by name. Not because the treaty is bad — because a choice that never mentions it is not a choice. If your team prefers the treaty's regime, keep it expressly instead. Decide; don't drift.
• Arbitration. A choice of law that is honored, an award that crosses borders, and one final instance. For buyers with enforceability concerns outside China's borders, this is usually the deciding feature.
• Language. English-language proceedings with translated evidence, in an institution that handles that routinely. The deeper bilingual-contract question — which version controls — is its own decision: which language controls your contract.

And one standing warning: whatever the master contract says, the transaction documents must not quietly replace it. A signed PI with different terms, or a chat confirmation you treated as an order, can rewrite the package — the PI-versus-contract problem defeats more well-drafted clauses than any court ever has.
