On Feb 24, 2023, Professor Jamie Peck of University of British Columbia, Canada visited CDI. CDI experts introduced the structure and recent developments of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). Afterwards, the two parties exchanged views on the GBA, particularly the coordination mechanism with respect to policy making and implementation. Both parties agreed that with three different legal systems, three different customs regimes and three different currencies, the GBA is distinct from the other world-renowned bay areas and faces a unique set of both opportunities and challenges. As a result, the governments are expected to explore and dynamically adjust the implementation pathway of GBA framework.
