The Outline Development Plan for the Guangdong-Hong Kong-Macao Greater Bay Area proposed to build an international education demonstration area, but the level of internationalization of higher education in Guangdong is not consistent with its economic status, especially in the field of higher vocational education. As international students being an important hallmark of the internationalization of higher education, Korea has achieved remarkable results in promoting the export of educational services and improving the internationalization level of universities, and its experience and lessons are worth learning. Through qualitative research methods such as historical review, literature analysis as well as online and offline interviews, this study examines and compares the strategies and policies adopted by Korea and Guangdong, Hong Kong and Macao in the internationalization of higher education. And then focused on the lessons and problems, recommendation of appropriate strategies and policies is provided to the higher vocational colleges and the education decision makers in GBA’s governments that are interested in expanding their efforts in recruiting the growing number of international students from overseas. As a large and strong province in vocational education, Guangdong has a lot of advantages in higher vocational education. Guangdong, Hong Kong and Macao are highly complementary to each other in promoting the internationalization of higher vocational education in GBA. The recommended solution is to deepen the reform and opening up and break down institutional barriers, to formulate development plans and do a good job in top-level design, to unveil special policies and enhance the construction of standards, to strengthen the teaching staff and speed up the popularization of Chinese, to encourage school-enterprise cooperation and improve the support systems.
