Recently Chinese President Xi Jinping opened the world’s longest sea-crossing bridge (55 km) connecting Hong Kong, Macau, and Zhuhai city in mainland China.
However, the bridge is also being seen as a part of a multi-pronged push by China to exert greater control over Hong Kong, which returned from British to Chinese rule in 1997 amid promises to preserve the city's high degree of autonomy and individual freedoms denied in mainland China.
The bridge was first proposed in the late 1980s, but it was opposed at the time by Hong Kong’s British colonial government, which was wary of development that might draw the city closer to Communist China.
The "Greater Bay Area" refers to the Chinese government's scheme to link the cities of Hong Kong, Macau, Guangzhou, Shenzhen, Zhuhai, Foshan, Zhongshan, Dongguan, Huizhou, Jiangmen, and Zhaoqing into an integrated economic and business hub.
