The 15th National Games, currently underway, have made history by involving Hong Kong and Macao as co-hosts for the first time in a national-level sports event. This unprecedented collaboration is seen as a significant milestone in the integration and development of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA). The event not only showcases the region’s ability to host large-scale international competitions but also strengthens ties between the mainland and the two Special Administrative Regions (SARs). Experts believe that this initiative will foster deeper economic, cultural, and social cooperation within the GBA, paving the way for a more unified and prosperous region. The Games serve as a platform to highlight the GBA’s potential as a global hub for sports, innovation, and collaboration.
