China's revised Arbitration Law, which enters into force on 1 March 2026, is the country's first comprehensive overhaul of its arbitration framework since 1995. The new law formally recognises the concept of the seat of arbitration, permits foreign arbitral institutions to administer cases on the mainland, and expands access to ad hoc arbitration for foreign-related disputes in designated free trade zones. For international companies with contracts seated in Hong Kong or with counterparties in mainland China, understanding the practical implications of these changes is now a priority.
Why This Reform Matters Now
Hong Kong has long operated as a distinct jurisdiction under the "one country, two systems" framework, with its own arbitration ordinance and a well-established track record at the Hong Kong International Arbitration Centre (HKIAC). The city's status as an international arbitration hub has rested partly on the clarity that a Hong Kong seat means Hong Kong law governs the conduct of proceedings, with enforcement routes through both the New York Convention and a dedicated arrangement with mainland China for mutual recognition of arbitral awards.
The 1995 mainland Arbitration Law contained no explicit concept of seat, which created long-running ambiguity about where disputes were truly "located" when parties chose a Chinese institution but sat outside the mainland. The incoming reform removes a significant source of that ambiguity. By codifying the seat doctrine, the revised law aligns China's framework more closely with international standards reflected in the UNCITRAL Model Law – a development that affects how mainland-connected contracts will be drafted and how existing arbitration clauses should be interpreted going forward.
Key Changes Under the Revised Law
- Recognition of seat of arbitration: For the first time, the mainland framework formally distinguishes the seat from the physical location of hearings. This has direct consequences for determining which courts have supervisory jurisdiction and which law governs the validity of an arbitral award enforcement application.
- Foreign institutions permitted to operate in China: The revised law allows foreign arbitral institutions – including those already active in Hong Kong such as the HKIAC – to administer cases on the mainland. The precise conditions, registration requirements, and any approval processes required by relevant mainland authorities are subject to implementing rules that remain pending as of the date of this alert.
- Expanded ad hoc arbitration: Ad hoc arbitration, previously available only in a limited domestic context, is now expressly permitted for foreign-related disputes in free trade zones. This brings the mainland closer to the more permissive Hong Kong position, where ad hoc arbitration has always been available, and may affect where sophisticated parties choose to structure their dispute resolution arrangements.
Who Is Affected in Hong Kong
The reform is directly relevant to any entity that negotiates, operates under, or enforces contracts with a mainland Chinese nexus. This includes companies listed on the Hong Kong Stock Exchange that are subject to SFC disclosure obligations when material disputes arise, as well as private equity funds and joint venture vehicles incorporated through the Companies Registry with mainland operating subsidiaries. Any party currently drafting or renegotiating a contract with a mainland counterparty should treat the incoming seat provisions as a structural consideration, not merely a procedural detail.
Existing contracts are equally worth reviewing. An arbitration clause written before 1 March 2026 that designates a mainland institution without specifying a seat may be interpreted differently once the revised law is in force. Parties relying on Hong Kong as the contractual seat should confirm that their clause is sufficiently explicit to withstand scrutiny under both the new mainland rules and Hong Kong's High Court supervisory framework.
Companies with pending or anticipated enforcement actions before the High Court Hong Kong should also take note. The alignment of mainland seat doctrine with international norms could affect arguments raised by opposing parties about where an award was "made" for the purposes of recognition and enforcement under the New York Convention.

Immediate Action Items for International Companies
Given that the effective date of 1 March 2026 is approaching, the following steps merit attention now:
- Audit existing arbitration clauses. Identify all contracts with mainland counterparties or those that designate a mainland institution. Assess whether the seat is explicitly stated and whether the clause is consistent with the framework you intend to apply after the revised law takes effect.
- Review new contract templates. Any arbitration clause being finalised for a foreign-related transaction should expressly designate the seat of arbitration, specify the governing law of the arbitration agreement itself, and confirm the chosen institution – whether HKIAC or another – rather than leaving these matters to implication.
- Monitor implementing rules. The conditions under which foreign institutions may operate on the mainland, and any approval or registration requirements, are not yet publicly codified. Companies that intend to rely on HKIAC or similar institutions for mainland-seated proceedings should track official guidance as it is issued.
- Assess pending enforcement proceedings. If you have an award at the recognition or enforcement stage in Hong Kong or on the mainland, consider whether the incoming seat provisions could be raised by the opposing party and take advice accordingly before 1 March 2026.
- Align dispute resolution strategy with corporate structure. The reform may create new strategic options – particularly the expanded ad hoc arbitration route in free trade zones – that were not available when existing structures were put in place. A review of your dispute resolution architecture alongside your broader corporate arrangements in Hong Kong is worth undertaking as part of routine planning.
The Hong Kong Seat – Still a Distinct Choice
Nothing in the mainland reform displaces Hong Kong's status as a separate arbitration jurisdiction. A dispute seated in Hong Kong remains governed by the Hong Kong Arbitration Ordinance, with the High Court Hong Kong retaining supervisory jurisdiction and awards remaining enforceable in over 170 jurisdictions through the New York Convention. What changes is the landscape around Hong Kong: mainland-seated proceedings will now operate under a more internationally legible framework, which may shift how parties weigh their options when selecting a seat of arbitration for cross-border contracts.
For companies that have historically defaulted to a Hong Kong seat precisely because of uncertainty about mainland procedures, the reform does not diminish the case for Hong Kong – but it does mean that the analysis should be conducted on updated information rather than assumptions formed before the overhaul.
Our litigation and arbitration practice in Hong Kong advises on seat selection, arbitration clause drafting, and the enforcement of awards across borders. We also work with clients on the corporate structuring aspects of cross-border arrangements through our corporate law practice in Hong Kong. We would be glad to walk through the implications of the revised mainland law for your contracts and dispute resolution planning.
A Note on Broader International Developments
The mainland reform does not stand in isolation. Questions about arbitrator disclosure obligations, the duty to disclose conflicts, and the grounds for challenging or removing arbitrators have been the subject of judicial and legislative attention in multiple jurisdictions. For clients managing multi-jurisdictional disputes, awareness of evolving standards across seats is increasingly important. Our analysis of arbitrator disclosure obligations in the United Kingdom provides useful context for understanding how disclosure standards are developing internationally, and how comparable questions may arise in Hong Kong-seated proceedings.
