Where enforcing a Hong Kong arbitral award in Mainland China stands now

An award creditor who wins in Hong Kong arbitration and then discovers the debtor's assets sit entirely on the Mainland faces a question that practitioners in London or New York cannot reliably answer: exactly how does that award cross the boundary, and where does the enforcement chain actually break under pressure? The answer has a specific legal architecture, and the architecture has moved.

Enforcing a Hong Kong arbitral award in Mainland China runs through the dedicated Mainland–Hong Kong arbitral-award enforcement Arrangements – not through the New York Convention – under the Arbitration Ordinance (Cap. 609) and the complementary regime that has applied since the 2020 Supplemental Arrangement, which permits simultaneous enforcement applications in both jurisdictions since its 2021 amendment. The cross-border interface is defined by treaty-level arrangements between two legal systems within one sovereign state, and it operates differently from any international enforcement route a foreign lawyer will have encountered.

This analysis maps the current position, identifies where the commercial risk concentrates, and offers our read on the enforcement questions that arise most often in practice.

What is commercially at stake when the assets are in the Mainland?

The asset endgame defines the entire arbitration strategy. Winning an award against a counterparty whose liquid assets, real property, and receivables are overwhelmingly situated in the Mainland People's Republic of China means that the enforcement step is not a formality – it is the matter itself.

In our cross-border practice, we regularly advise award creditors who have conducted textbook arbitrations: well-drafted clauses, Hong Kong seat, HKIAC administration, a well-reasoned final award. The problem emerges at enforcement. The debtor's operating subsidiaries, bank accounts, and land-use rights are all in the Mainland. The creditor's leverage is only as strong as its ability to reach those assets through the Mainland people's courts.

That reality produces a strategic calculation that should, in principle, begin at the contract-drafting stage. Which seat produces an award that the Mainland courts will receive? Under what conditions will they refuse? What interim measures are available before and during arbitration to preserve the asset position? These questions are not theoretical. They determine whether the award has commercial value or is simply an expensive piece of paper.

The stakes are amplified by the asset types commonly in play. Real property in the Mainland – including commercial premises, land-use rights, and industrial facilities – requires enforcement through the people's court where the property is situated. Bank accounts follow the branch. Equity interests in Mainland entities trigger their own procedural requirements. A single award may require coordinated enforcement actions in multiple Mainland court districts simultaneously.

What is the governing regime, and how does the cross-border interface actually operate?

The Mainland–Hong Kong arbitral-award enforcement regime operates through two instruments: the 1999 Arrangement on Mutual Enforcement of Arbitral Awards between the Mainland and the Hong Kong Special Administrative Region, and the 2020 Supplemental Arrangement, the key amendment to which took effect in 2021 and introduced the right to bring simultaneous enforcement applications in both places at once.

The New York Convention does not govern this route. Hong Kong is a party to the Convention, but because Hong Kong and the Mainland form part of the same sovereign state, the cross-boundary mechanism operates through these dedicated Arrangements rather than through treaty. This is one of the most consequential distinctions in cross-border enforcement practice, and it is one that foreign counsel consistently underestimate.

Under the Arrangements, a Hong Kong-seated award that has been made final and binding is capable of enforcement in the Mainland people's courts. The applicant presents the award and the underlying arbitration agreement to the relevant Mainland court. The court then applies a defined set of grounds on which it may refuse enforcement. Those grounds track – but do not replicate – the refusal grounds in the New York Convention. Practitioners familiar only with Convention enforcement need to examine the specific grounds in the Arrangements carefully.

The 2021 amendment to the Supplemental Arrangement is the most significant procedural development in recent years. Before 2021, an award creditor who applied to enforce in one jurisdiction was ordinarily expected to wait before bringing a corresponding application in the other. The amendment removed that constraint. A creditor now has the ability to apply simultaneously in both Hong Kong and the Mainland – a structural change that improves asset-preservation leverage considerably.

Separately, the interim-measures Arrangement that came into force on 1 October 2019 introduced a mechanism by which a party to a Hong Kong-seated arbitration may apply to a competent Mainland people's court for interim measures – including asset preservation orders – before or during the arbitration, without waiting for a final award. This is a significant tool that sits upstream of enforcement proper, and it materially changes the risk calculus for creditors with Mainland counterparties.

The sequence that flows from these two instruments – interim measures during arbitration, simultaneous post-award enforcement on both sides of the boundary – gives the diligent award creditor a more complete toolkit than existed even five years ago. The question is whether practitioners are using that toolkit in the correct order.

How do the two legal systems compare at the enforcement stage?

The Mainland people's courts and the Hong Kong courts occupy different positions in the enforcement picture, and understanding that difference is not a formality – it is the substance of cross-border enforcement planning.

Hong Kong operates a common-law system with English as an official working language of the courts. The Court of First Instance is the seat of first-instance civil enforcement. The doctrine of binding precedent applies. The institutional culture of the courts is shaped by generations of commercial-law development, and the judiciary's treatment of arbitral awards is well-established. The Arbitration Ordinance (Cap. 609) is modelled on the UNCITRAL Model Law, and Hong Kong courts have consistently taken a pro-enforcement posture.

The Mainland people's courts operate under a civil-law system with different institutional assumptions. Enforcement of foreign and cross-boundary awards passes through a hierarchical court structure. Higher courts play a significant supervisory role in cases involving international or cross-boundary enforcement. That hierarchy has historically served as a review mechanism that, in earlier years, produced uncertainty; subsequent institutional reforms at the Mainland level have tightened the grounds on which lower courts can refuse enforcement, and the direction of travel has been toward greater predictability.

Where the two systems meet most visibly is in the treatment of public policy as a refusal ground. Both the Mainland regime and the Convention framework carry a public-policy exception. In practice, Mainland courts have applied this ground with varying scope, and the parameters are not static. An award that addresses a claim with regulatory dimensions – licensing, foreign investment restrictions, or certain securities-related obligations – carries a higher residual risk of public-policy objection than a straightforward commercial-debt award.

The comparative picture also differs by asset type. In Hong Kong, the Court of First Instance can make orders over a wide range of asset classes efficiently. Mainland enforcement of an asset-preservation order or a final award against a Mainland bank account or land-use right requires engagement with the court in the relevant district and compliance with distinct procedural requirements. Counsel on our desk regularly see enforcement files where the creditor has obtained a solid award but has made no advance preparation for the Mainland-side procedural steps, producing avoidable delay.

One specific divergence concerns the treatment of non-signatory parties and group-of-companies arguments. Hong Kong courts have addressed these questions in the context of the Arbitration Ordinance. Mainland courts approach the same questions from a different doctrinal starting point. An enforcement strategy that relies on extending the award's reach to related Mainland entities needs to account for that divergence from the outset.

How does the interim-measures route change the strategic picture?

The interim-measures Arrangement that took effect in October 2019 fundamentally altered the pre-award position for creditors with Mainland counterparties. For the first time, a party to a Hong Kong-seated arbitration could apply to a designated Mainland people's court for property preservation, evidence preservation, or conduct preservation – before a final award had been issued.

That capability matters because Mainland debtors who anticipate an adverse award have, in some cases, attempted to dissipate or restructure assets during the arbitration period. The ability to freeze Mainland assets at an early stage – while the arbitration is still proceeding – places the creditor in a structurally stronger position.

The application is made to a designated Mainland court. The arbitral institution must be on the list of approved institutions for the purposes of the Arrangement; the HKIAC, as the principal Hong Kong arbitral institution, is included. The application presents evidence of the asset at risk and the potential award. Mainland courts have processed these applications, and the mechanism has demonstrated practical utility in our experience.

What practitioners sometimes overlook is the relationship between interim measures and the subsequent enforcement filing. The interim-measures order preserves assets; it does not itself enforce the award. Once the award is issued, the creditor must still bring the full enforcement application. The interim-measures step buys time; it does not substitute for a well-prepared enforcement file. Sequencing these two stages correctly – and timing the interim-measures application relative to the arbitration timetable – is a practical decision that should involve Hong Kong-side counsel familiar with both the HKIAC Rules and the Mainland procedural requirements.

An Asian industrial group we advised in this context (a Mainland-counterparty dispute, mid-market value, HKIAC seat, winter 2024) applied for property preservation at the point where asset-dissipation risk became apparent during the arbitration. The property-preservation order was granted by the designated Mainland court and remained in place through the award stage. The enforcement filing proceeded on the preserved asset base. The sequential design of that strategy – not the award itself – produced the commercial outcome.

Where does the risk actually concentrate now?

The enforcement regime is, by historical standards, well-developed. The risks that remain are structural, not incidental. Understanding where they sit determines whether a creditor approaches enforcement with appropriate preparation or discovers the obstacles at the wrong moment.

The first concentration of risk is at the arbitration-agreement stage. The Arrangements require a valid arbitration agreement as a condition of enforcement. If the agreement is ambiguous as to seat, ad hoc rather than institutional, or drafted in a form that creates any doubt as to the parties' consent to Hong Kong arbitration, the Mainland court has grounds to examine that question at the enforcement stage. This is a drafting risk, and it is not recoverable once a dispute has arisen.

The second is the public-policy ground. As noted, the Mainland courts retain the ability to refuse enforcement on public-policy grounds. The scope of this exception is not defined with precision in the Arrangements. Awards that address claims in sectors with heavy regulatory overlay – financial services, real estate, foreign-investment-restricted industries – carry a higher exposure here. The risk is not eliminated by having a well-reasoned award; it is reduced by understanding the regulatory dimension of the underlying claim from the outset.

The third is the duzhao (duplicate enforcement or asset-conflict) risk that arises when enforcement is pursued in multiple Mainland districts against dispersed assets without coordination. Different district courts may issue inconsistent orders, or enforcement against one asset class may inadvertently exhaust the debtor in a way that prejudices recovery from a more accessible asset. Coordination across Mainland-side enforcement actions requires a clear asset map prepared before the first filing.

The fourth risk is procedural delay. Mainland enforcement proceedings have their own timetable, and the creditor has limited ability to accelerate the process. Interim measures, where available, mitigate but do not eliminate the timing risk. For creditors with genuine time pressure – a counterparty in financial difficulty, for example – the enforcement plan needs to account for realistic Mainland-side processing timelines, not optimistic ones.

The fifth is reciprocity and political context. The Arrangements operate at the level of institutional arrangements between two legal systems. They are not treaties in the international sense, and they are subject to the broader relationship between the Mainland and Hong Kong legal authorities. That relationship has, in recent years, moved in a direction that has expanded the mutual-enforcement architecture. The interim-measures Arrangement and the 2020 Supplemental Arrangement are evidence of that trajectory. There is no objective basis for pessimism about the direction of travel, but practitioners should track any institutional developments that may affect the regime's scope.

If an earlier enforcement attempt has produced a stalled result or an adverse procedural outcome, a second read of the file can identify the strategic point of failure and the routes that remain available. Email info@lockhartyip.com to discuss your position.

What does the enforcement sequence look like in practice?

The practical enforcement sequence for a Hong Kong-seated award against a Mainland debtor runs through a defined set of stages, each of which produces its own decision points.

At the pre-award stage, the strategic question is whether to apply for interim measures in the Mainland people's courts. The conditions are: a valid arbitration agreement, a Hong Kong seat, a qualifying institution, and an identifiable Mainland asset at risk. If those conditions are met and there is any indication of dissipation risk, the interim-measures application should be considered before the tribunal's proceedings are complete.

At the award stage, the creditor needs to ensure the award is in final form and that the correct formalities have been observed for cross-border enforcement. The award should address the enforcement dimensions from the outset – the correct identification of the debtor, the specification of the relief granted, and the absence of formal defects that would invite procedural objection in the Mainland court. A well-constructed HKIAC award satisfies these requirements as a matter of standard practice. An ad hoc award needs careful attention.

At the application stage, the creditor presents the award and the arbitration agreement to the relevant Mainland people's court. The court examines whether the statutory grounds for refusal are engaged. The creditor's counsel on the Mainland side needs to be prepared for potential public-policy objection, challenge to the arbitration agreement's validity, or service-related procedural arguments. Each of these requires a pre-prepared response.

The simultaneous-application right introduced by the 2021 amendment means the creditor need not choose between Hong Kong-side and Mainland-side enforcement. Both can run concurrently. In practice, the Hong Kong-side enforcement position – which is ordinarily straightforward for a Hong Kong-seated award – provides a negotiating backstop while the Mainland application proceeds.

The final stage is execution against specific assets. This is where the Mainland-side procedural requirements become most granular: the correct court district, the asset-class-specific rules, the involvement of enforcement officers, and the practical mechanics of realising value from the frozen or encumbered asset. Experience in this final stage – across different Mainland court districts and different asset types – is the distinguishing element in effective enforcement practice.

A decision matrix in prose helps clarify the approach:

Where the debtor has liquid Mainland bank accounts and the award is final: the simultaneous application route under the 2020 Supplemental Arrangement is the primary instrument; timing is the principal variable; the interim-measures route was relevant if dissipation risk was identified during arbitration.

Where the primary asset is a Mainland land-use right or real property interest: the enforcement application must go to the district court where the property is situated; coordination with Mainland-side counsel familiar with that district is essential; the public-policy risk is generally lower for a clean property-debt claim.

Where the debtor is a Mainland group with dispersed subsidiaries and the award runs against the parent: the creditor needs an asset map before filing; the question of whether the award can be extended to subsidiary-level assets requires analysis of the Mainland corporate-law position alongside the enforcement regime.

Where the award was rendered in a non-institutional Hong Kong arbitration: the validity of the arbitration agreement and the formal requirements for recognition will be examined more closely; the creditor should expect a more substantive procedural engagement at the Mainland court stage.

What do foreign counsel consistently get wrong?

In our cross-border practice, we see a recurring set of errors that originate not from bad intentions but from the application of enforcement frameworks that do not apply in the Mainland–Hong Kong context.

The most common is the assumption that the New York Convention controls. It does not, as discussed. A US-qualified or EU-qualified disputes lawyer who knows the Convention well may not know the Arrangements at all. The Arrangements have a different scope, different refusal grounds, and a different institutional framework. Applying Convention assumptions to a Mainland enforcement problem produces incorrect strategic advice.

The second error is treating the Mainland people's courts as a monolithic institution. In practice, enforcement experience varies considerably across court districts, across asset types, and across the level of court. A generalised view that "Mainland courts are difficult" is less useful than a specific understanding of the enforcement environment in the district where the relevant asset is located.

The third error is sequencing the interim-measures step too late. The interim-measures Arrangement is a pre-award tool. By the time the award is issued, if the debtor has restructured its Mainland asset position, the value of the award has already been reduced. Counsel who have not advised on the interim-measures route before and during arbitration have missed the most important asset-preservation window.

The fourth is an incomplete arbitration agreement. Foreign-law-qualified drafters sometimes produce arbitration clauses that are ambiguous as to seat, or that specify ad hoc rules in a way that creates doubt about institutional requirements under the Arrangements. These drafting choices, which may be entirely standard in another context, create unnecessary enforcement risk in the Mainland context.

A European principal we advised in this context (a cross-border commercial dispute, substantial claim, Hong Kong-seated HKIAC arbitration against a Mainland counterparty, spring 2025) had received initial advice from its home-jurisdiction counsel that the New York Convention would apply and that enforcement would follow a standard Convention route. When the enforcement step was reached, the Convention framework was inapplicable. We mapped the correct route under the Arrangements, identified the relevant Mainland court district, and prepared a coordinated simultaneous-application filing. The enforcement process advanced on the correct procedural basis.

Where this is heading: our read on the current position

The direction of the Mainland–Hong Kong enforcement architecture has been consistently expansionary. The 1999 Arrangement established the basic mutual-enforcement mechanism. The 2019 interim-measures Arrangement added a pre-award asset-preservation tool that has no equivalent in most bilateral enforcement regimes globally. The 2020 Supplemental Arrangement and its 2021 amendment introduced simultaneous enforcement applications.

Each of these developments has moved in one direction: expanding the tools available to the award creditor with Mainland assets. There is no structural reason to expect that trajectory to reverse. The institutional interests of both the Mainland legal system and the Hong Kong arbitration community are served by a functional mutual-enforcement architecture.

The outstanding question is not whether the regime will continue to develop, but whether practitioners are using what already exists. In our experience, the most common cause of enforcement failure is not the absence of a legal route – it is the failure to identify and use the correct route at the correct stage. The interim-measures tool is underused. The simultaneous-application right is insufficiently understood. The asset-mapping step before filing is routinely skipped.

The commercial environment in which this regime operates has also evolved. Mainland counterparties in cross-border disputes are increasingly sophisticated in their knowledge of the enforcement environment. Some will test the procedural requirements carefully at the enforcement stage, raising arguments about arbitration-agreement validity or public policy that require a well-prepared response. The creditor who arrives at the enforcement stage with a complete file – valid agreement, institutional award, identified assets, pre-prepared responses to anticipated objections – is in a materially stronger position than one who has treated enforcement as an afterthought.
