With the evolution of industrial structure and industrialization in developing countries, some trade has become intra-industry between developing and developed countries. The level of intra-industry trade between China and South Korea has also become an essential indicator of the country’s economic development and industrialization. Since the establishment of diplomatic relations between China and South Korea in 1992, bilateral trade between China and South Korea has steadily developed, and the “Belt and Road” initiative proposed by China in 2013 and the official signing of the China-South Korea Free Trade Agreement (FTA) in 2015 have provided a good platform for the development of trade between China and South Korea. In 2017 South Korea proposed in 2017, South Korea proposed the “New North Policy”, and China and South Korea agreed to dovetail the “Belt and Road” and the “New North Policy” to achieve a superior development of China-Korea trade. However, there are still problems, such as trade imbalance and a need for a two-way flow of investment between the two sides. This paper examines the existing problems in developing China-Korea import and export trade through developing China-Korea intra-industry trade in the new era. It suggests accelerating the sustainable development of China-Korea trade from the perspectives of strengthening trade communication between the two sides and accelerating Chinese enterprises’ investment in Korea.
