The China arbitration clause — CIETAC, offshore seats, and the mistakes that make an award unenforceable

The clause you sign at the start of a China contract — not the dispute that erupts three years later — decides whether you can ever collect. Get the arbitration clause right and a favourable award is bankable in Beijing, Singapore or London. Get it wrong — a non-existent institution, an offshore seat for a purely domestic dispute, or a muddle between arbitration and the courts — and the clause itself can be void, leaving a good case with nothing to enforce. Dispute prevention starts on the day you draft, not the day you fall out.

Onshore or offshore? The foreign-related test decides what you can even choose

Before you weigh CIETAC against Singapore, PRC law decides whether the choice is open to you at all. The long-standing rule is that only a foreign-related dispute may be submitted to arbitration seated outside mainland China. Send a purely domestic dispute offshore and a Chinese court can hold the arbitration agreement invalid — the worst possible outcome, because you discover it only when you try to enforce.

The trap that catches foreign investors is that a wholly foreign-owned enterprise (WFOE) registered in China is a Chinese legal person. A contract between your China WFOE and a Chinese supplier, both incorporated onshore and performing in China, can look domestic — with no automatic right to an offshore seat. A genuine foreign element (a foreign party, offshore performance, an asset abroad) is what unlocks the choice.

There is a targeted relaxation. In the Golden Landmark line of cases, Chinese courts accepted that a dispute between two WFOEs registered in a free trade zone could be treated as foreign-related, so their agreement to arbitrate abroad would not be struck down merely for lacking an obvious foreign element. It is a carve-out, not a general licence. If your structure is onshore-onshore, assume you are arbitrating in China unless counsel confirms otherwise. We map these threshold questions in our dispute resolution practice.

CIETAC, HKIAC or SIAC — choosing the forum

Of China's 200-plus arbitration commissions, CIETAC (the China International Economic and Trade Arbitration Commission) is the one foreign parties reach for most; the Beijing Arbitration Commission (BAC/BIAC) and SHIAC in Shanghai are credible onshore alternatives. Offshore, the HKIAC in Hong Kong and the SIAC in Singapore are the regional heavyweights. CIETAC has also run a Hong Kong Arbitration Center since 2012, giving you a CIETAC-administered arbitration seated in Hong Kong.

The real trade-off is neutrality and enforcement versus proximity to the assets:

• CIETAC (mainland seat) — award enforces directly in China as a domestic or foreign-related award, without a treaty step. Best when the counterparty's assets are in China and speed of enforcement matters.
• HKIAC / CIETAC Hong Kong — a neutral common-law seat whose awards enforce in the mainland under the Mainland–Hong Kong arrangement, and elsewhere under the New York Convention.
• SIAC (Singapore) — a fully offshore, neutral seat; awards enforce in China under the New York Convention. Popular where both sides want distance from either home forum.

All three lead to an enforceable award if the clause is clean — the differences are cost, neutrality, interim relief and the enforcement route. That last point is where the value of the clause is realised, so draft it with enforcement in mind: see enforcing a foreign arbitration award or judgment in China.

What a clean clause must actually say

A serviceable China arbitration clause is short but specific. It should fix, in plain terms, five elements:

• The institution, by its exact official name. “Arbitration in Beijing” is not enough; name CIETAC, HKIAC or SIAC precisely.
• The seat. The seat determines the supervisory court and the procedural law — it is not the same as the hearing venue, and it drives how the award is later classified and enforced.
• The governing law of the contract — and, ideally, a separate line stating the law governing the arbitration agreement itself. The two can differ, and specifying the second closes off a common validity fight before it starts.
• The language. If you say nothing, a CIETAC arbitration proceeds in Chinese — a real disadvantage for a foreign party. State English, or a bilingual proceeding, expressly.
• The tribunal. Set the number of arbitrators (one or three) and, for a three-member tribunal, consider requiring a presiding arbitrator of neutral nationality.

The pathological clauses that make an award unenforceable

Most unenforceable awards trace back to a clause that was defective from day one. The recurring failures:

• A misnamed or non-existent institution. A clause pointing to a body that does not exist, or that cannot be identified from the wording, risks being held invalid. Copy the institution's own model clause rather than paraphrasing.
• “Arbitration or litigation” optionality. A clause that lets a party choose between arbitration and the courts is, under Chinese practice, generally treated as no valid arbitration agreement at all. Pick one path.
• Ad hoc arbitration seated onshore. Chinese law has historically required institutional arbitration. As set out below, the 2026 reforms open ad hoc arbitration only in narrow foreign-related pockets — an ad hoc clause seated in the mainland for an ordinary commercial contract remains a trap.
• A silent or contradictory seat. Leaving the seat unstated, or naming two, invites a jurisdictional fight that can outlast the underlying dispute.

None of these is exotic. Each is avoidable with ten minutes of drafting discipline — and each, uncorrected, is the reason a winning award turns out to be worthless.

The 2026 Arbitration Law — and drafting backwards from enforcement

China's revised Arbitration Law took effect on 1 March 2026 (adopted 12 September 2025). It modernises the framework in ways foreign parties should note. It codifies the “seat of arbitration” for foreign-related cases, so party choice of seat now has a clear statutory footing. It permits ad hoc arbitration for the first time — but only for foreign-related maritime disputes and for disputes between enterprises registered in designated free trade zones and the Hainan Free Trade Port. And it allows approved foreign arbitral institutions to administer foreign-related arbitrations in those zones. These are meaningful openings, not a wholesale change: for the ordinary cross-border contract, a clearly drafted institutional clause remains the safe path.

Whichever forum you choose, the acid test is enforcement. A mainland-seated award enforces in China directly; a foreign-seated award (Singapore and other Convention states) enforces via the New York Convention, to which China has been party since 1987; a Hong Kong award enforces under the Mainland–Hong Kong mutual enforcement arrangement, updated by a 2020 supplemental arrangement, on grounds that largely mirror the Convention. Draft the clause backwards from where the assets sit and how you would collect — that discipline is what turns a dispute clause into a genuine remedy. The mechanics are in enforcing a foreign award or judgment in China, and the wider practice in dispute resolution.
