Update: a compliance review before contracting with a Mainland China entity
A compliance review before contracting with a Mainland China entity. What changed and the action it now calls for. Write to info@lockhartyip.com.
Cross-border payment channels between Hong Kong and Mainland China have come under heightened scrutiny. The Anti-Money Laundering and Counter-Terrorist Financing Ordinance imposes customer due diligence obligations on any business using Hong Kong as a contracting or settlement hub – and those obligations are triggered at the point of engagement, not at the point of payment failure.
A compliance review before contracting with a Mainland China entity is a structured pre-execution check of the counterparty's identity, ownership chain, source of funds, and sanctions exposure under applicable United Nations measures, conducted under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance before any binding agreement is signed.
This briefing sets out what has sharpened the requirement, who it affects across the Hong Kong–Mainland corridor, and the immediate action it calls for.
What has changed – and why the timing matters now
Three developments converge. First, Hong Kong implements United Nations sanctions and does not give domestic effect to unilateral measures of other states. That distinction matters: a counterparty that appears on a unilateral list of another jurisdiction may still engage Hong Kong banking channels, but a counterparty that appears on a UN-designated list cannot – and the consequences of proceeding without a check are severe.
Second, the Foreign States Immunity Law of the People's Republic of China has been in force since 1 January 2024. It introduces a restrictive immunity doctrine with direct implications for cross-border enforcement against state-connected Mainland entities. Where a Mainland counterparty carries state ownership or mandate, the structure of the contract and the compliance file must reflect that exposure from the outset.
Third, regulators across the corridor have signalled elevated expectations for correspondent banking due diligence (the checks a bank performs on entities that route payments through its accounts). A contract that lacks a documented compliance review creates friction at every subsequent stage: at payment initiation, at banking onboarding, and – if a dispute arises – in enforcement proceedings.
In our sanctions and AML practice, we see this pattern repeatedly: the compliance gap is not discovered at the point of signing. It surfaces later, when a payment is flagged, a bank requests documents that do not exist, or enforcement counsel finds the file does not support the claim.
Who is affected across the Hong Kong–Mainland corridor
The requirement applies broadly. Any entity using Hong Kong as a contracting hub, a settlement currency, or a payment relay for Mainland China transactions carries this obligation. The affected population includes: international groups with Mainland operating entities or joint-venture counterparties; family-office principals investing in Mainland assets through Hong Kong holding structures; fund managers with Greater China portfolio companies; and in-house teams managing supply-chain contracts with Mainland manufacturers or distributors.
The obligation is not limited to large transactions. The Anti-Money Laundering and Counter-Terrorist Financing Ordinance applies by counterparty category, not by contract value. A small but structurally complex Mainland counterparty – one with layered ownership, state-connected affiliates, or sector exposure in areas subject to UN measures – can create a disproportionate compliance burden if addressed late.
The immediate action
The review has three parts. First, identity and ownership: confirm the Mainland entity's registered name, unified social credit code (China's national business identifier), registered address, and ultimate beneficial owner to the applicable threshold. Where the ownership chain passes through a Hong Kong or offshore intermediate, trace it to the natural person.
Second, sanctions screening: run the entity and its principals against current UN consolidated lists. Document the screen and its date. Where the entity operates in a sector or geography with elevated UN-measures exposure, record the basis for the conclusion that no designation applies.
Third, source-of-funds and payment channel: confirm that the proposed payment route – typically a Mainland renminbi account to a Hong Kong correspondent bank – is consistent with the entity's stated business and that no intermediary in the chain carries an unexplained exposure.
The file produced by this review serves multiple functions: it satisfies the bank's documentary requirements, it creates an evidentiary record if the relationship is challenged, and it supports any subsequent enforcement step in Hong Kong or before a Mainland court. We regularly act on cross-border matters where the compliance file – or its absence – determines the outcome of a later dispute.

The sequence described above should be completed before any binding term sheet or framework agreement is signed. Once the counterparty relationship is established, retroactive remediation is significantly more difficult and – where a payment has already moved – may not be available at all.
Frequently asked questions
What documents are needed for a compliance review before contracting with a Mainland China entity?
The core documents are: the entity's business licence (showing the unified social credit code and registered name), ownership and beneficial ownership information traced to the natural person, a current UN sanctions screen with date, and records confirming the proposed payment channel. For state-connected entities, documentation of any government ownership or mandate is also required. The precise scope turns on the entity's sector and ownership structure.
What is the first step in a compliance review before contracting with a Mainland China entity?
The first step is confirming the Mainland entity's legal identity: its registered name, registration number, and the jurisdiction of incorporation or registration. From that foundation, the ownership chain is traced and the UN sanctions screen is run. The review cannot proceed reliably until the identity question is answered, because the screen and the source-of-funds inquiry both depend on it.
Do I need a Hong Kong adviser for a compliance review before contracting with a Mainland China entity?
Cross-border counsel with experience in the Hong Kong–Mainland corridor adds material value at two points: structuring the review to meet Hong Kong banking and regulatory expectations, and ensuring the file supports enforcement if the relationship later deteriorates. The Anti-Money Laundering and Counter-Terrorist Financing Ordinance is Hong Kong-specific; a Hong Kong-informed review is not the same as a generic corporate due diligence exercise.
