Not a blood alliance anymore: China's evolving policy toward UN sanctions on North Korea.

What has driven China's policy toward United Nations (UN) sanctions on North Korea? While insisting on a peaceful settlement of North Korean nuclear issues via diplomatic dialogues, China has gradually loosened its protective stance regarding UN sanctions on North Korea. This article examines the factors that have pushed China to take a tougher position toward North Korea: North Korea's increasingly aggressive nuclear policy, the influence of the United States on Chinese foreign policy, and the changing perception of North Korea in China. Through close examination of China's domestic discussions on North Korea, this article concludes that, besides the external factors, a growing negative perception of North Korea has played an increasingly important role in changing China's official stance. The findings suggest that closer attention should be paid to the changes in the domestic political environment of China to understand its current and future approach toward North Korea.
