The rapid growth of cross-border e-commerce is changing the global trade pattern, and each country is vigorously promoting the development of cross-border e-commerce in order to take the initiative in the new global trade pattern. In June 2015, China set up the chapter on “e-commerce” in China-Korea FTA for the first time. Since the establishment of diplomatic relations between China and Korea for more than 20 years, the total trade volume between the two countries has increased by nearly 50 times. The two countries promote the growth of e-commerce through cooperation and win-win. The e-commerce between China and Korea is developing rapidly, but the cross-border e-commerce market and business model of the two countries are quite different. With the increase in the scale of cross-border e-commerce import and export, how to effectively monitor the entry and exit of goods while meeting the needs of domestic and foreign consumers is a common problem faced by China and Korea. This paper analyzes the development characteristics of cross-border e-commerce in the two countries from the macro level of cross-border e-commerce import and export scale, import and export countries, import and export products, settlement methods, transportation methods, import and export customs clearance, and national policies. Finally, combined with the development characteristics of cross-border e-commerce between China and Korea, and the status quo of cross-border e-commerce cooperation between China and Korea, some suggestions are put forward.
