The development of the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) standards can promote the interconnectivity and integrated development of the three places, deepening Hong Kong's economic and trade exchanges and co-operation with the Chinese Mainland and Macao.

These GBA standards are drawn up after the Guangdong authorities' liaison with various relevant groups and enterprises from the trade, related government departments and organisations, universities and experts in Guangdong, Hong Kong and Macao, and are formulated after public consultations. Currently, a total of 262 GBA Standards have been formulated and promulgated, covering the fields of food quality and safety, Cantonese cuisine, prepared dishes, transportation, mechanical and electrical products, as well as medical care, nursing care, education, e-sports and "environmental, social and governance" etc.
