Drafting an HKIAC arbitration clause for a Mainland China counterparty

A commercial contract with a Mainland China counterparty is only as useful as the dispute-resolution mechanism it contains. Counsel on our desk see this regularly: a foreign principal signs a well-negotiated agreement, the relationship sours, and the arbitration clause turns out to be the weakest point in the document. The clause was drafted in general terms, the seat is ambiguous, and the enforceability question – where the award actually lands and against what assets – was never properly thought through at the contracting stage.

Drafting an effective HKIAC arbitration clause for a Mainland China counterparty requires a precise choice of seat (Hong Kong), governing rules (the HKIAC Administered Arbitration Rules, the institutional rules of the Hong Kong International Arbitration Centre), and a clear pathway to enforcement under the Arrangement between Mainland China and Hong Kong on the mutual enforcement of arbitral awards – the mechanism that makes an HKIAC award recoverable against assets on the Mainland. The clause must be drafted as part of the contract, not appended as an afterthought, and the asset endgame must be mapped before the ink dries.

This page sets out when a foreign principal needs this work done, the route we run, the decisions the client must own, and the cross-border enforcement position that determines whether the clause performs when it matters.

When does this become urgent – and why do foreign principals leave it too late?

The trigger is almost always a relationship in motion: a joint-venture negotiation, a distribution or supply agreement, a technology-licensing deal with a state-adjacent counterparty, or an acquisition of a Mainland operating entity. The foreign principal's home-jurisdiction counsel drafts the main operative terms; the dispute-resolution clause is treated as a standard annexe. That is where the exposure begins.

A clause that names a seat outside Hong Kong – or no seat at all – closes the door to the Mainland–Hong Kong mutual-enforcement Arrangements. A clause that selects an ad hoc (non-institutional, unadministered) process creates procedural gaps that a well-resourced Mainland party can exploit. A clause that selects HKIAC but omits the seat, the governing rules version, or the language of proceedings leaves three live disputes before the arbitration even begins.

The urgency is structural. Once the contract is signed and the relationship is in place, renegotiating the dispute-resolution clause requires the counterparty's consent. That consent is rarely forthcoming when the relationship is already under strain. What starts as a drafting problem becomes a negotiating problem, and then an enforcement problem. The time to correct it is before execution.

The Arbitration Ordinance (Cap. 609) – the Hong Kong statute that governs arbitral proceedings seated in Hong Kong, modelled on the UNCITRAL Model Law – gives the Hong Kong courts supervisory jurisdiction over HKIAC-seated arbitrations. That supervisory jurisdiction is what makes interim measures and enforcement applications before the Hong Kong courts available. It does not arise where the seat is elsewhere.

What does a properly drafted HKIAC clause actually contain?

An enforceable HKIAC clause for a Mainland China counterparty has six operative elements, each of which requires a deliberate decision rather than a default. Generic model clauses are a starting point, not an endpoint.

The first element is the designation of HKIAC as the administering institution and the HKIAC Administered Arbitration Rules as the governing procedural rules. The current rules are the 2024 Rules, in force from 1 June 2024. Reference to "HKIAC rules" without a version marker may create a question about which rules apply where the parties signed under an earlier version.

The second element is the seat of arbitration. Hong Kong must be named expressly. The seat determines the supervisory court, the applicable arbitral-procedure law, and – critically – whether the mutual-enforcement Arrangements with the Mainland apply. An ambiguous seat clause is litigated, not assumed.

The third element is the language of the arbitration. For Mainland China counterparties, a bilingual election – Chinese and English – or a single-language election with translation obligations for documentary evidence is a practical necessity. The choice affects tribunal composition, document production, and the timetable.

The fourth element is the number of arbitrators. A three-person tribunal is standard for mid-to-high-value commercial disputes. A sole arbitrator is permissible under the HKIAC Rules for lower-value or less complex matters. The clause should make the election; if it does not, HKIAC decides, and the outcome may not match either party's expectation.

The fifth element is the governing law of the contract. The arbitration clause is separable from the main agreement, but the governing law of the underlying contract determines the substantive law the tribunal applies. Where Mainland Chinese law governs the contract, the client needs to understand what that means for the claims available, the defences the counterparty will run, and the documentation the tribunal will require.

The sixth element is the scope of disputes submitted to arbitration. An overly narrow clause – "disputes arising out of this clause" instead of "disputes arising out of or in connection with this agreement" – can exclude claims that are plainly within the commercial intent of the parties. That exclusion is exploited in litigation. The scope must be as broad as the parties intend and no broader.

How does the cross-border enforcement position shape the drafting?

The enforceability question is the centre of gravity for every HKIAC clause where the counterparty is Mainland Chinese and the assets are on the Mainland. Drafting the clause without mapping the enforcement pathway is like designing a building without a load calculation.

The mutual enforcement of arbitral awards between Mainland China and Hong Kong operates under two instruments: the 1999 Arrangement on Mutual Enforcement of Arbitral Awards between the Mainland and the HKSAR and the 2020 Supplemental Arrangement, which came into effect with a material amendment permitting simultaneous enforcement applications in both jurisdictions. Since that amendment, an award creditor with assets on both sides of the boundary is no longer required to choose one forum and exhaust it before applying in the other.

This is the mechanism that makes HKIAC the practical choice for contracts with Mainland China counterparties. A non-Hong Kong award – from a Singapore, London, or Paris-seated institution – reaches the Mainland under the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards. That is a longer and more variable route than the bilateral Mainland–Hong Kong Arrangement. The Arrangement has a track record; the Convention route, while legally available, carries greater procedural uncertainty before the Mainland people's courts.

What this means for drafting is concrete. The clause must establish the conditions for the Arrangement to apply. Hong Kong must be the seat. HKIAC must be identified as an arbitral authority recognised under the Arrangement. The award must be final and binding. Any carve-out that leaves a category of disputes to Mainland courts – a waiver clause that excludes certain claims from arbitration – breaks the enforcement mechanism for those claims and creates a parallel litigation risk.

We also advise on the interim-measures pathway. Since 1 October 2019, parties to a Hong Kong-seated arbitration may apply to the Mainland courts for interim measures – asset preservation, evidence preservation, injunctive-type relief – before the award is issued. This is the Arrangement Concerning Mutual Assistance in Court-ordered Interim Measures in Aid of Arbitral Proceedings by the Courts of the Mainland and of the Hong Kong SAR. The application is made through HKIAC. For a contract with a Mainland counterparty holding significant Mainland assets, the ability to seek interim measures on the Mainland before the award is issued can be determinative. The clause must not inadvertently close that door.

For related enforcement considerations involving judgment recognition across the boundary, our service on recognising court judgments from the United Kingdom in Hong Kong sets out the parallel recognition framework.

The step-by-step route we run – and where locally licensed counsel join

Our cross-border practice structures this engagement in four phases. The client owns the commercial decisions; we own the legal architecture.

The first phase is the asset and enforcement map. Before a single word of the clause is drafted, we identify where the counterparty's assets sit, what categories of dispute are most likely, and what interim-measures exposure exists. This shapes every subsequent decision. A Mainland counterparty whose assets are entirely within a single province and sector presents a different enforcement map from one with offshore holding entities, Hong Kong accounts, and cross-border trade receivables.

The second phase is the clause architecture. We draft the arbitration clause – seat, rules, language, tribunal composition, scope, governing law interaction – and annotate the decisions for the client. The annotation is not a formality. Clients who understand why the clause reads the way it does are in a better position to resist counterparty pressure during negotiation and to instruct a tribunal correctly if the dispute arises.

The third phase is negotiation support. Mainland counterparties – and the advisers who act for them – frequently push back on HKIAC as the seat or the institution. The most common objections are: a preference for CIETAC (the China International Economic and Trade Arbitration Commission, a PRC-based arbitral institution), a preference for Mainland courts, or a proposal for a split mechanism that routes certain claim types to Mainland courts and others to Hong Kong arbitration. We prepare the client to respond to each objection with a principled position, not a capitulation.

The fourth phase is integration with the main agreement. The arbitration clause does not operate in isolation. The governing-law clause, the notice provisions, the representation and warranty structure, and the limitation-of-liability provisions all interact with the dispute-resolution mechanism. We review the agreement as a whole to ensure consistency and to identify any drafting that would complicate enforcement.

Locally licensed Hong Kong firms join at the point where Hong Kong law advice is required – including on the interaction between the Arbitration Ordinance and the clause, on any court-filing steps, and on matters of Hong Kong procedural law. We coordinate that relationship and maintain instruction continuity throughout.

The sequence above describes the standard position. Your matter turns on the documents, the jurisdictions actually engaged, and the order of steps – which is where the route is won or lost. To discuss your cross-border contract position, write to us at info@lockhartyip.com.

What decisions does the client need to own before instructing counsel?

Our role is to give the client the legal architecture. Several decisions, however, can only be made by the commercial principal, and arriving at the first meeting with clarity on each of them accelerates the work and sharpens the clause.

The first decision is the value threshold for arbitration. If the commercial relationship involves recurring transactions of varying sizes, the client should consider whether a sole-arbitrator track for lower-value disputes makes sense alongside a three-person tribunal for major claims. HKIAC provides for this. The clause can make the election by reference to a claim value.

The second decision is the counterparty's likely posture. A state-owned enterprise will approach dispute resolution differently from a private Mainland company. The former is more likely to rely on domestic jurisdiction arguments; the latter may be more commercially pragmatic about a neutral forum. The clause should be calibrated accordingly, and the client should be prepared to walk away from a deal where the counterparty refuses any form of neutral arbitration.

The third decision is the asset endgame. If the principal expectation is that an award would need to be enforced against Mainland assets, the clause must support the Mainland–Hong Kong Arrangement pathway. If enforcement against Hong Kong assets is more likely – because the counterparty has accounts or receivables in Hong Kong – the Hong Kong enforcement route is simpler. If both are possible, the clause must not foreclose either.

The fourth decision is the governing law of the contract. Clients sometimes resist specifying a governing law for commercial reasons – they do not want to concede that Mainland or home-jurisdiction law applies. Leaving the governing law unspecified creates a substantive-law dispute as a threshold matter in any arbitration. That threshold dispute costs time and money. A choice – even an imperfect one – is almost always preferable to no choice.

A micro-scenario illustrates the stakes. A European technology company entered a long-term licensing arrangement with a Mainland software distributor. The agreement was negotiated in English; the arbitration clause selected Hong Kong as the seat but named no institution and no rules. When the relationship deteriorated, the Mainland party argued that the reference to "Hong Kong arbitration" meant ad hoc arbitration under the UNCITRAL Arbitration Rules and that HKIAC had no jurisdiction. The European principal spent a significant portion of the likely damages on a jurisdiction phase alone. Had the clause named HKIAC and the applicable rules, that phase would not have arisen. The fix was a single sentence at the drafting stage.

What gets contested in negotiations – and how to hold the position

The most common point of resistance from Mainland counterparties is the institution. CIETAC is proposed as an alternative on the basis that it is more familiar to Mainland parties and that its awards are directly enforceable in the Mainland. That proposition is partly accurate and partly a negotiating position. CIETAC awards made in Beijing or Shanghai are enforceable in the Mainland under domestic PRC enforcement rules. They are also potentially enforceable in Hong Kong under the Arrangement. But a foreign principal enforcing a CIETAC award in Hong Kong is not in a materially better position than one enforcing an HKIAC award in the Mainland. The neutrality argument – that HKIAC, as a Hong Kong institution, is independent of both the Mainland legal system and the foreign principal's home system – is the more powerful response.

The second point of resistance is the seat. A Mainland counterparty may propose Shanghai, Beijing, or a PRC free-trade-zone seat. The foreign principal should understand that a Mainland-seated arbitration is supervised by the Mainland courts and falls outside the HKIAC Administered Arbitration Rules in their standard form. It also removes access to the Hong Kong courts' supervisory jurisdiction and to the interim-measures Arrangement in its current form. That is a material concession for which there should be a material commercial offset.

The third point of resistance is the language. Proposing Chinese as the sole language of arbitration is a legitimate position, but it creates asymmetry if the client's primary documents, witness evidence, and legal team are English-language. A bilingual election is the commercially rational compromise. It adds modest procedural overhead; it avoids the risk that the evidentiary record is shaped by translation rather than by the underlying facts.

A second illustrative scenario: an Asian holding group with a BVI parent entity entered a joint-venture agreement with a Mainland counterparty. The counterparty's counsel proposed CIETAC, Beijing seat, Chinese language. After structured negotiation, the parties agreed on HKIAC, Hong Kong seat, bilingual proceedings, sole arbitrator below a stated claim threshold, and three arbitrators above it. The holding group's ability to articulate the enforcement rationale – specifically, the interim-measures Arrangement and the simultaneous-enforcement amendment – was determinative in securing the Hong Kong seat. The counterparty's counsel acknowledged that the enforcement position was materially equivalent; the dispute was about familiarity, not substance. The matter closed in autumn 2025. For further context on joint-venture dispute dynamics, see our matter note on shareholder and joint-venture disputes involving a BVI partner.

If an earlier filing, structure, or enforcement attempt produced an adverse or stalled result, a second read can identify the strategic error and the routes still open. Write to us at info@lockhartyip.com to discuss the options.

Common mistakes foreign counsel make – and the points they miss

Foreign counsel – particularly those based in US or continental European jurisdictions – bring drafting habits that do not translate cleanly to the Mainland China context.

The most consequential error is treating the arbitration clause as jurisdiction-agnostic. A clause modelled on standard ICC or AAA language, with a neutral seat in a third country, performs well in transatlantic disputes. Against a Mainland China counterparty holding Mainland assets, it produces an award that must travel to the Mainland via the New York Convention route rather than the bilateral Arrangement. That is a longer, less predictable enforcement path.

The second error is drafting carve-outs (exceptions that route specific claims to a different forum) without understanding the enforcement consequences. A carve-out sending intellectual property disputes to the Mainland courts may seem commercially reasonable – IP is sensitive in Mainland China, and domestic courts may have stronger remedial tools for interim injunctive relief. But it creates a parallel litigation track, and the interaction between that track and the arbitration produces sequencing problems that neither set of rules contemplates.

The third error is omitting the interim-measures provision or failing to advise the client that an interim-measures application on the Mainland is available from an HKIAC-seated arbitration. The asset-preservation mechanism – available since 1 October 2019 – is one of the most practically significant features of a Hong Kong seat for Mainland-counterparty contracts. Counsel who draft the clause without flagging this feature leave the client uninformed about one of the principal reasons to choose HKIAC.

The fourth error is failing to coordinate the arbitration clause with the governing law clause. A contract governed by PRC law, with an HKIAC seat, requires the tribunal to apply Mainland substantive law. That is procedurally workable but requires advance thought about expert-evidence requirements, document production, and the Mainland legal concepts that will govern the merits. Counsel who draft the clause in isolation, without reading the governing-law provision, produce a document that works on its own terms but creates practical difficulty when a dispute arises.

Our Disputes & Arbitration practice covers the full lifecycle from clause drafting through to award enforcement and the interaction with the Mainland–Hong Kong recognition and enforcement architecture.

The checklist before you sign

Before executing any commercial contract with a Mainland China counterparty, the following questions should be answered – not by reference to a model clause, but on the facts of the specific deal.

Is the seat of arbitration expressly stated as Hong Kong? Is HKIAC named as the administering institution, with the HKIAC Administered Arbitration Rules – and the applicable version – identified? Is the language of the arbitration specified? Is the number of arbitrators set by the clause, or left to HKIAC's determination with a stated preference? Does the scope of disputes submitted to arbitration cover all claim types the client may need to bring? Is the governing law of the contract specified, and has the interaction with the arbitration clause been reviewed? Are there any carve-outs, and has the enforcement consequence of each been considered? Has the interim-measures Arrangement been explained to the client and its availability under the clause confirmed? Is the enforcement map – where the counterparty's assets sit – documented and used to verify that the clause supports the preferred enforcement route?

If the answer to any of these questions is unclear, the clause is not ready to sign. These are not formalities; they are the load-bearing elements of the dispute-resolution structure.
