The Korea-China cooperative partnership model achieved the dual goal of working-level cooperation between the two countries and effective control over structural contradictions and guaranteed the rapid development of bilateral relations. but structural conflicts between the two countries, the two systems, and the two security systems still persist. These structural conflicts have been hampered by factors such as changes in the dynamics of the two countries, widening the gap in strategic perceptions, and deteriorating cooperation environment. This study summarized the achievements and limitations of the Korea-China strategic cooperation partnership as follows. First of all, economic cooperation between Korea and China is shifting from a complementary relationship to a competitive phase. Next, the progress of the Korea-China strategic partnership has prepared a strategic environment for the development of bilateral relations. However, there is a gap between the official regulations and the actual situation.hird, it is the expansion of humanities exchanges and sluggish understanding between the people of the two countries. Humanities exchanges have been actively conducted between Korea and China based on geographical proximity and historical and cultural similarities.The mutual feelings of the people of the two countries cannot follow the development trend of bilateral relations, but on the contrary, they are showing a deteriorating atmosphere. This paper argues that China and Korea should make the following efforts in the future. First, Korea and China should actively promote the momentum for cultural exchange. Second, Korea and China should maintain and improve the safety of supply chain cooperation. Third, Korea and China should improve the sustainability of the communication mechanism between the two countries.

“The rise of China” is a critical issue of the twenty-first century’s world politics. China is leading the new bipolar system in the post-Cold War period with the US. As the American dominance in East Asia became weaker, the old containment could not be fully implemented anymore. As a result, a new comprehensive strategic initiative covering the whole Pacific coastal States is being adopted. The outcome of this transformation is the Trans-Pacific Partnership (TPP), which was reached on October 5, 2015. This article aims to analyze the newly arisen TPP as a post-Cold War strategic alliance of East Asia. The TPP is a mega regional trade agreement. Its predictable legal setting is thus indispensable for the peaceful coordination of competition between both sides. The TPP could be a firm ground for the stability of this region, sharing the vision of cooperation, not confrontation in the future.
