Building the Greater Bay Area city cluster is a crucial national development strategy for China. As a vital hub of the Belt and Road Initiative, the Greater Bay Area cannot cultivate into an “international first-class bay area and world-class city cluster” without technological innovation and rapid economic progress, and technological innovation and economic development cannot be attained without the training of high-end talents through international education. Thus, the development of an international education demonstration zone is essential in the formation and development of the Greater Bay Area and making it a highland for education and talent, as well as giving full play to the social function of education. As the core of the accumulation of educational resources in Guangdong, Hong Kong, and Macao, the current situation, future opportunities, and development path of international education development in the Greater Bay Area while building a world-class international education center have become the starting point of this study.
