Guangdong-Hong Kong-Macau Greater Bay Area


The Guangdong-Hong Kong-Macau Greater Bay Area or simply Greater Bay Area, is a megalopolis, also known as the Pearl River Delta, consisting of nine cities and two special administrative regions in south China. On 7 December 2016, the concept for the area was mentioned in the English version of China's 13th Five-Year Plan.
On 13 April 2017, the heading of a piece of news released at the English.gov.cn website of the State Council adopted the name "Guangdong-Hong Kong-Macao Bay Area". Just over two months later, on 1 July 2017, the "Framework Agreement on Deepening Guangdong - Hong Kong - Macau Cooperation in the Development of the Bay Area" was signed in Hong Kong.
The GBA consists of Guangzhou, Shenzhen, Zhuhai, Foshan, Dongguan, Zhongshan, Jiangmen, Huizhou, and Zhaoqing, as well as Hong Kong and Macau.
