The Closer Economic Partnership Arrangement (“CEPA”) amendment between mainland China and Hong Kong, effective 1 March 2025, expands market access for Hong Kong businesses. Covering trade in goods, services, investment, and economic cooperation, CEPA now includes liberalisation measures in sectors like construction, financial services, and tourism. Key updates include easing equity ownership limits and professional service restrictions. Hong Kong enterprises can also capitalize on premier legal and arbitration services for Mainland operations. While most measures apply nationwide, select pilot initiatives focus on the Greater Bay Area, highlighting enhanced integration and opportunities for Hong Kong-based companies in a growing market.
