China tightens scrutiny of outbound investments via Hong Kong

New outbound investment regulations in China are reducing Hong Kong’s appeal as a primary route for moving mainland capital, technology, and data overseas. The 'Regulations on Outbound Investment', which took effect on 1 July, introduce a national security review system and establish new approval and filing requirements for mainland Chinese residents making foreign investments.

Legal experts note that the rules specifically target technology-intensive transactions and aim to close gaps regarding the outbound flight of sensitive assets. The regime is designed to combat 'offshore washing', a practice where mainland Chinese intellectual property, data, or technology is transferred to holding companies in jurisdictions like Singapore or the Cayman Islands before being sold through offshore transactions.

Furthermore, the regulations increase scrutiny on indirect transfers involving overseas personnel deployment and training. According to Joanne Du, a partner at Mayer Brown LLP, the new security review regime materially undermines the 'white glove' advantage Hong Kong previously offered for less transparent corporate and private wealth structures.
