Where acquiring a Mainland China target through a Hong Kong vehicle stands now

The question is not whether Hong Kong remains a viable acquisition vehicle for Mainland China targets. It is whether the team assembling the structure understands precisely where each element sits – and where the deal can fail. For foreign groups entering Mainland China through a Hong Kong holding entity, that question is sharper today than at any point in the past decade. Regulatory perimeters on both sides of the boundary have been redefined. The allocation of risk between the onshore and offshore layers has shifted. And the sequence in which consents, registrations and approvals are obtained now determines whether the structure holds at closing and beyond.

Acquiring a Mainland China target through a Hong Kong vehicle requires alignment across two legal systems – common law above the boundary, civil law below it – and involves at minimum the Hong Kong Companies Ordinance (Cap. 622), the Mainland regulatory approval regime for inbound foreign direct investment, and the commercial-law instruments that govern the underlying transaction. The Mainland Judgments in Civil and Commercial Matters (Reciprocal Enforcement) Ordinance (Cap. 645), in force since 29 January 2024, adds a post-closing enforcement dimension that now shapes how Hong Kong-governed transaction documents are structured from the outset.

This analysis sets out what is commercially at stake, where the governing regime bites, how the two systems compare and where, in our view, the concentration of risk sits for deals being assembled today. It draws on our cross-border M&A practice and speaks directly to general counsel and principals who have a deal at the evaluation or structuring stage.

What is actually at stake commercially

The commercial logic of the Hong Kong vehicle remains strong. Hong Kong occupies a unique position as a common-law jurisdiction that sits at the boundary of the world's second-largest economy. A Hong Kong incorporated entity provides the offshore acquirer with a recognisable legal personality governed by a well-tested body of company law, English-language courts and a tax regime with no capital gains charge and 16.5% corporate profits tax above the two-tier threshold. Those features have real economic value when structuring a cross-border acquisition.

Yet the commercial stakes on the Mainland side are equally material. The target – whether a wholly foreign-owned enterprise, an equity joint venture or a variable interest entity structure – carries regulatory status that the acquisition must preserve or convert without triggering a review that stops the deal. Capital repatriation, profit distribution and the eventual exit route all depend on the offshore holding layer interacting correctly with the onshore entity. Get any part of that interface wrong, and the acquirer may hold a structurally defective asset from day one.

What has changed most sharply in the past several years is the enforcement environment. A Hong Kong judgment or arbitral award on a deal dispute can now reach Mainland assets through a more direct route than was available before. That changes the negotiating position at the transaction documentation stage, and it changes the risk calculus for sellers and acquirers alike. Our desk regularly advises principals who factor this enforcement upgrade into the deal structure from the first term sheet – rather than treating it as a post-closing concern.

How does the governing framework operate across the two systems?

The Hong Kong vehicle sits in a legal environment that is common law in character: statutes are interpreted by the courts using common-law methods, judgments bind lower courts by precedent, and the English language is an official working language of the judiciary. The Companies Ordinance (Cap. 622) governs the Hong Kong entity's constitution, share structure and director obligations. Transaction documents governed by Hong Kong law – sale and purchase agreements, shareholder agreements, share charges, completion mechanics – operate within that framework.

Below the boundary, the target is governed by a materially different system. Mainland China operates a civil-law regime with mandatory provisions that cannot be contracted out. The approval and registration of the foreign investment is governed by the Foreign Investment Law and its implementing regulations, administered primarily by the Ministry of Commerce and the State Administration for Market Regulation. Where a target operates in a sector subject to restricted or prohibited-category rules under the Negative List for foreign investment, the structure must either accommodate those restrictions or reconfigure the ownership layer accordingly.

The cross-border interface bites at a number of points that are not always visible at the term-sheet stage. First, there is the question of variable interest entity (VIE) structures – contractual arrangements used historically to give foreign investors economic exposure to Mainland businesses in restricted sectors without formal equity ownership. Regulatory clarity on VIE structures has evolved, and the compliance position of any VIE-based target must be assessed in full before the Hong Kong vehicle acquires the contractual interest. Second, foreign exchange and capital controls under the administration of the State Administration of Foreign Exchange create a mandatory overlay on how acquisition proceeds flow and how dividends and sale proceeds are later repatriated. Third, data-related compliance – including the Personal Information Protection Law and the Data Security Law – now affects target-side due diligence and, in some cases, requires regulatory filing before a foreign acquirer can access certain categories of target-side data.

For the Hong Kong vehicle specifically, the Companies Ordinance requirements on the acquirer entity – share issuance, director resolutions, the Significant Controllers Register – must be maintained in parallel with the Mainland approval sequence. The Significant Controllers Register requirement, in force since 1 March 2018, means that the beneficial ownership chain above the Hong Kong vehicle is a matter of record from the moment of incorporation, and that chain must be consistent with the ownership structure disclosed in the Mainland approval filings.

The contextual bridge between these two regimes is the set of bilateral arrangements between Hong Kong and the Mainland. The mutual enforcement framework for arbitral awards – the 1999 Arrangement and the 2020 Supplemental Arrangement – and the mutual recognition of judgments under Cap. 645 create a post-closing enforcement corridor that can be used affirmatively, or that a counterparty can use against the acquirer. Parties should structure the dispute-resolution clause in the Hong Kong-layer transaction documents with that corridor explicitly in mind.

The comparative read: what Hong Kong offers that other vehicles do not

Foreign groups assembling Greater China acquisitions frequently consider alternative holding locations: Singapore, the British Virgin Islands, the Cayman Islands, or a European jurisdiction through which a double-taxation treaty can be accessed. Each has genuine advantages. But Hong Kong's combination of features is distinctive and, in our view, remains unmatched for deals where the target is a Mainland China operating business.

The tax position is the first distinguishing element. Hong Kong imposes profits tax on a territorial basis – only on Hong Kong-sourced profits. Capital gains are not taxed. Dividends from Hong Kong entities are not subject to withholding tax in the general position. The two-tier profits tax regime – 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above – means that, for a holding vehicle earning management fees or royalties sourced in Hong Kong, the effective rate can be materially lower than in most alternative holding centres. The foreign-sourced income exemption (FSIE) regime, in force from 1 January 2023, applies economic-substance conditions to certain passive income streams flowing through the Hong Kong entity; acquirers must ensure the Hong Kong vehicle has the requisite substance before relying on the exemption.

For groups within the scope of the Pillar Two global minimum tax – those with consolidated group revenue at or above EUR 750 million, for fiscal years beginning on or after 1 January 2025 – Hong Kong's minimum top-up tax applies. This does not eliminate the structural advantage of Hong Kong, but it changes the modelling, particularly for holding layers that previously relied on an effective rate well below 15%. Counsel assembling the vehicle must run the Pillar Two calculation for the Hong Kong entity as part of the pre-signing structure review.

The second distinguishing element is proximity and connectivity. A Hong Kong vehicle can interface with Mainland counterparts, regulators, banks and courts in the same time zone, in Chinese, through personnel who are physically close to the target. Singapore offers a well-tested legal system and an extensive tax-treaty network, but it does not have the same proximity to the Mainland's regulatory bodies, and its enforcement corridor to Mainland courts and arbitral institutions is less developed than Hong Kong's. The BVI and Cayman are efficient holding layers but typically sit above a Hong Kong vehicle rather than replacing it; they do not provide the same direct interface with the Mainland approval regime.

The third element – and the one that has gained in significance most recently – is the enforcement corridor. The Cap. 645 regime, which brought a new basis for registering effective Mainland judgments with the Court of First Instance and for using Hong Kong judgments in Mainland proceedings, removed the old requirement that the parties have agreed to exclusive jurisdiction. It introduced a connection-based test instead. What this means in practice is that a Hong Kong-governed share purchase agreement, where one party later obtains a Hong Kong judgment on a breach claim, now has a more direct route to enforcement against Mainland assets than was available under the predecessor regime. For an acquirer negotiating representations, warranties and indemnities in a Mainland target acquisition, that is a material change to the risk allocation, and it should be priced into the deal structure.

Where the risk sits now: our read on the current position

In our cross-border M&A practice, the concentration of risk in acquisitions of this type has shifted from the structural layer to the approval and substance layer. A decade ago, the primary risk was getting the corporate architecture right – the holding chain, the share structure, the governed-law provisions. Those elements remain important, but they are well-understood. The risk that is less well-managed, in the transactions our desk reviews, sits in three areas.

The first is approval sequencing. The Mainland approval process for a foreign acquisition involves multiple regulators – commerce, market regulation, potentially cybersecurity – and the sequence in which those approvals are obtained and the condition precedent structure of the transaction must be calibrated precisely to that sequence. Deals that close before all required approvals are obtained, or that treat certain regulatory steps as post-closing conditions that are in fact mandatory pre-conditions, can result in the structure being void or voidable under Mainland law. The Hong Kong vehicle is then holding an asset without a clean legal title.

The second is VIE-layer due diligence. Where the target includes a VIE structure, the due-diligence scope must extend to the contractual enforceability of each VIE agreement under current Mainland law and regulatory guidance. VIE enforceability has been a contested area, and the position has shifted over time. An acquirer who takes ownership of the Hong Kong entity holding the VIE contracts without a full assessment of that position may be acquiring a structure that the Mainland courts would not enforce, or that the relevant regulator has the power to unwind.

The third is substance at the Hong Kong level. The FSIE regime and, for larger groups, the Pillar Two minimum top-up tax, require that the Hong Kong vehicle have genuine economic substance if it is to be treated as the beneficial owner of income flows and to avoid top-up tax. In our experience, acquirers from jurisdictions where holding-company substance requirements are less developed – parts of Central Asia, the Middle East and Eastern Europe – sometimes treat the Hong Kong entity as a pure pass-through. Under the current regime, that approach generates both a tax risk and, depending on the facts, an AML/compliance risk in relation to source-of-funds filings at the Hong Kong banking level.

Consider a scenario our desk has encountered on several occasions. A European industrial group structures the acquisition of a Mainland manufacturing business through a freshly incorporated Hong Kong special-purpose vehicle. The deal team completes the Hong Kong corporate steps correctly, but the Mainland approval filing is submitted before the target has obtained a required sector-level consent. The sellers, aware of the gap, have structured the representations to exclude regulatory approvals not yet obtained. At completion, the acquirer holds the Hong Kong vehicle, which holds a contractual entitlement to the Mainland equity, but the underlying registration of the foreign investment has not been completed. The practical enforcement of that entitlement depends on the willingness of the Mainland target's directors to cooperate with a registration process that has no mandatory deadline. Two years after signing, the registration remains incomplete. The enforcement route available to the acquirer – via the Hong Kong-governed share purchase agreement, through Cap. 645 registration with the Court of First Instance – is real, but it is slower and more expensive than completing the approval sequence before closing. The lesson our desk draws from matters of this kind is that the approval matrix must be built into the condition precedent structure, not treated as a post-signing administrative step.

A second scenario illustrates the FSIE point. An Asian family office sets up a Hong Kong holding company to acquire a Mainland consumer brand. The deal is structured to route royalty income from the Mainland operating company through the Hong Kong entity. In the first year of operation, the IRD issues enquiries about the substance of the Hong Kong entity's royalty-holding function. The entity has a registered address and a nominal director, but no employees in Hong Kong and no decision-making genuinely carried out at the Hong Kong level. The FSIE regime requires economic substance for the royalty income to qualify for the exemption. The result is a retroactive tax exposure at the Hong Kong level and an amendment required to the group's Pillar Two computation. The lesson is that substance cannot be added after the event. It must be built into the Hong Kong entity's governance model from the date of incorporation.

Decision matrix: matching the situation to the right route

The appropriate structure and approval route depend on the intersection of target characteristics, sector, acquirer profile and deal objectives. In our experience, the following matrix captures the dominant situations our clients face.

Where the target is a wholly foreign-owned enterprise in a generally open sector, and the acquirer is a recognised foreign entity with no sanctions-adjacent exposure, the standard Hong Kong vehicle with a Hong Kong-governed share purchase agreement and sequential Mainland approval filings is the baseline route. The primary risk variable is timing – the Mainland approval process can extend well beyond initial estimates – and the condition precedent structure must give the deal adequate breathing room without creating a situation in which the long-stop date expires before approvals arrive.

Where the target is in a restricted sector under the Negative List, the Hong Kong vehicle layer must be assessed together with a Mainland legal team that can advise on whether any form of equity or quasi-equity participation is permissible. If it is not, a minority economic-rights structure or a management agreement may be the only available form of exposure. In that situation, the enforceability of those arrangements in a distress scenario – through the Cap. 645 corridor or through Mainland arbitration under the China International Economic and Trade Arbitration Commission – is the central legal question, and it should be the subject of a specific advisory note before the term sheet is signed.

Where the target has a VIE structure, the acquisition must be structured at the VIE-agreement level, not merely at the holding-company equity level. The acquirer should obtain specific advice on whether the assignment or novation of VIE contracts is permissible under their terms and under the applicable Mainland regulatory guidance, and whether the acquisition of the offshore entity that holds those contracts carries the full economic and legal exposure intended. Our desk sees a recurring pattern where the acquirer has focused on the offshore share purchase without fully modelling what happens to the VIE contracts in an enforcement scenario.

Where the deal involves a target whose data assets are a significant part of the value – whether user data, proprietary datasets, or operationally critical digital infrastructure – the data compliance layer must be assessed as part of pre-signing due diligence. The filing or approval requirements under the data-security regulatory regime can affect both the due-diligence timeline and the closing condition structure.

What foreign counsel and deal teams consistently get wrong

Our cross-border M&A practice encounters consistent patterns of error in deals of this type. The most common is treating the Hong Kong vehicle as a neutral layer that simply holds the Mainland equity. It is not neutral. The Hong Kong entity is the legal acquirer, the party to the transaction documents, the subject of the FSIE and Pillar Two analysis, and – critically – the entity whose legal personality and standing the Mainland approval filings recognise. Any change to the Hong Kong entity's ownership, constitution or regulated status after the Mainland approvals are obtained may trigger a fresh approval obligation.

The second common error is using a template share purchase agreement designed for a pure common-law transaction without adapting the representations, warranties and condition precedent structure to the Mainland regulatory approval sequence. A representation that the target has all necessary regulatory approvals is meaningless if it is given at a date before the Mainland registration of the foreign investment is complete. The representation schedule must map to the actual regulatory sequence.

The third error is underestimating the banking and AML layer at the Hong Kong level. The Hong Kong vehicle will require a bank account. In the current compliance environment, Hong Kong banks apply detailed source-of-funds enquiries to newly incorporated entities acquiring Mainland targets, particularly where the acquirer is from a jurisdiction on the Financial Action Task Force's monitoring list or where the target operates in a sector associated with compliance risk. Deals that do not plan for a two-to-four month account-opening process at the Hong Kong entity level can face a closing delay that has nothing to do with the transaction's legal structure.

The fourth error – observed particularly in deals involving acquirers who have not previously used Hong Kong as a holding location – is conflating the Hong Kong common-law system with the Mainland system. The two systems share a national framework but operate on materially different legal foundations. Counsel from jurisdictions with experience in one but not the other – a European firm advising on a first-time Asia acquisition, or a Mainland-focused practice advising on the offshore layer without a common-law-trained counterpart – will frequently miss the interface points that our desk is specifically positioned to identify.

Addressing this pattern directly: what foreign counsel consistently get wrong is treating the cross-border interface as a series of administrative steps rather than as a set of legal questions each of which requires a position paper before the transaction proceeds. The approval sequence, the VIE-contract assignment, the FSIE substance analysis, the Cap. 645 enforcement corridor – each of these is a discrete legal analysis that must be completed before the next step is taken. A deal team that treats them as parallel tasks to be managed simultaneously will frequently find that a gap in one analysis invalidates the work done in another.

The enforcement and exit angle

Exit planning is rarely the primary concern at the acquisition stage. But in our view, it should be built into the structure from the outset. The Hong Kong vehicle's exit options depend on where the value sits – in the Mainland equity, in the VIE contracts, in a licence or distribution arrangement – and on the regulatory conditions attached to the original inbound approval.

For a straightforward equity exit – sale of the Hong Kong vehicle to a new foreign buyer, or sale of the Mainland equity from the Hong Kong vehicle to a Mainland buyer – the Cap. 645 regime is relevant in two directions. First, if the exit produces a dispute, a Hong Kong judgment on the sale-and-purchase terms can be registered and enforced against Mainland assets of the relevant counterparty. Second, if the Mainland counterparty obtains a Mainland judgment on a related claim, it can seek registration of that judgment with the Court of First Instance and, if registration is granted, enforce against the Hong Kong vehicle's assets. The symmetry of the regime means that both parties can use the corridor. Structuring the exit documentation with awareness of that symmetry – choice of law, choice of dispute resolution, scope of indemnities – is the correct approach.

For a listing exit – taking the group public on the Hong Kong Stock Exchange or on a Mainland market – the Hong Kong vehicle's clean legal title to the Mainland equity, confirmed by the Mainland registration, is a prerequisite. Any ambiguity in the approval chain from the original acquisition will be identified in the pre-listing due diligence and will either delay the listing or require a restructuring that is significantly more expensive than getting the approvals right at the acquisition stage.

Our desk regularly acts on matters where an earlier acquisition was completed with a structural defect – an incomplete approval, a VIE assignment that was not properly effected, a substance gap at the Hong Kong level – and the client is seeking a remedial path ahead of an exit or a secondary acquisition. Remediation is possible in most cases, but it is time-consuming and, in the current regulatory environment, involves engagement with Mainland regulators that can attract scrutiny of the original transaction. The stronger position is to address the analysis correctly at the acquisition stage.

Self-assessment: key questions before the structure is finalised

Before the term sheet is signed and the Hong Kong vehicle is incorporated, a deal team should be able to answer a defined set of questions. Can the acquisition be structured as a direct equity purchase, or does the target's sector position require a restricted or VIE-based approach? Has the Mainland approval sequence been mapped against the condition precedent structure, and is the long-stop date calibrated to the realistic timeline for each approval stage? Does the Hong Kong vehicle have, or will it have, the economic substance required under the FSIE regime for the income flows the structure is intended to route?

Is the dispute-resolution clause in the Hong Kong-governed transaction documents designed with awareness of the Cap. 645 enforcement corridor? Has the source-of-funds position at the Hong Kong banking level been assessed against the current AML requirements? For groups with consolidated revenue at or above EUR 750 million, has the Pillar Two minimum top-up tax been modelled for the Hong Kong entity? And – a question that is deceptively simple but frequently unanswered at the term-sheet stage – is the beneficial ownership chain above the Hong Kong vehicle consistent, in every particular, with what will be disclosed in the Mainland approval filings and recorded in the Significant Controllers Register?

If any of these questions lacks a clear answer, the structure is not ready to proceed. Our desk can work through each of these points with the deal team and prepare the position papers and structuring notes that will support the advice from the locally licensed Hong Kong and Mainland counsel who are handling the jurisdiction-specific execution.
