Cai Guanshen pointed out that to build a world-class urban agglomeration, how to break the barriers of the system and mechanism of the three regions and achieve seamless connection is a crucial matter. To this end, he suggested that the European Union could be used as a reference for the development of high-quality and high-standard regional cooperation, learning from the point to the face, from the easy to the difficult, from the specific practice to the legal system, and finally establishing a mature and developed common market through fault-tolerant tests and continuous improvement, so as to help the Great Bay Area realize the free flow of goods, services, personnel and capital.

"As an important support for the 'the Belt and Road' construction, the Guangdong Hong Kong Macao Greater Bay Area should also jointly 'go global'." At the beginning of this year, Cai Guanshen led a Hong Kong business delegation of about 70 people jointly organized by the Hong Kong Chinese General Chamber of Commerce, the Guangdong Hong Kong Macao Greater Bay Area Entrepreneur Alliance, and the Hong Kong Vietnam Chamber of Commerce to visit Vietnam, promoting in-depth cooperation between ASEAN and the Guangdong Hong Kong Macao Greater Bay Area.
