China-North Korea trade accounts for the majority of North Korea’s international trade and is considered significant for the economic development and social stability of North Korea. Due to the fourth North Korean nuclear test and the subsequent UN sanctions resolution, the current situation and future prospects of China-North Korea trade are becoming increasingly relevant to the peace and stability of the Northeast Asian region. This paper examines recent trends in China-North Korea trade and analyzes the causes of the ongoing decrease and its prospects, before discussing possible effects and policy implications of a prolonged downturn.
