On July 1, 2017, the National Development and Reform Commission (NDRC) and the governments of Guangdong, Hong Kong Special Administrative Region and Macao Special Administrative Region jointly signed the “Agreement on Deepening the Cooperation between Guangdong, Hong Kong and Macao” to build the Guangdong-Hong Kong-Macao Greater Bay Area (GBA)".

Two years since, the region has become a world-class bay area. The GBA bears witness to the spirit of the "one country, two systems" principle and has become a new highlight of China's high quality development.
