The Guangdong-Hong Kong-Macao Greater Bay Area (hereinafter the 'Greater Bay Area') refers to a city cluster consisting of two special administrative regions, Hong Kong and Macao, and nine cities in the Guangdong province, namely Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Zhaoqing. The concept of the Greater Bay Area has attracted considerable public attention since March 2016 when it was included in China's 13th Five-Year Plan (2016-2020), the blueprint for the country's economic and social development. It was highlighted again in the government work reports for 2017 and 2018, further indicating that the development of the Greater Bay Area is a key item in the agenda of the Chinese government. On 18 February 2019, the Chinese authorities unveiled the Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area (hereinafter the Plan), bringing the concept one important step closer to actualization. According to the Plan, the development of the Greater Bay Area is not only a new attempt in China's further opening up, but also a further step in taking forward the practice of 'one country, two systems'.
