Between 1980 and 1984, China established special economic zones (SEZs) in Shantou, Shenzhen, and Zhuhai in Guangdong Province and Xiamen in Fujian Province and designated the province of Hainan a special economic zone. Early Chinese business concerns in the CNMI are traceable to these zones.
In 1984, China opened 14 coastal cities to overseas investment in Dalian, Qinhuangdao, Tianjin, Yantai, Qingdao, Lianyungang, Nantong, Shanghai, Ningbo, Wenzhou, Fuzhou, Guangzhou, Zhanjiang, and Beihai.
In 1985, it established more economic zones in the Liaodong Peninsula, Hebei Province (which surrounds Beijing and Tianjin), Shandong Peninsula, Yangtze River Delta, Xiamen-Zhangzhou-Quanzhou Triangle in southern Fujian Province, Pearl River Delta, and Guangxi.
In 1990 the State Council opened the Pudong New Zone in Shanghai to overseas investment.
