Second, countries like the United States that still exhibit the Cold War mentality have exploited the perceptual disagreements among states and hampered their joint efforts to counter mutual security threats such as terrorism. This is irrational and irresponsible, especially because the need is to shelve the differences over ideologies and work for regional and global peace and security.

The constructive exchanges between Beijing and Seoul on security issues are a step toward a healthy "new normal" in bilateral and even multilateral cooperation, marked by equal importance to every country's efforts, to maintain regional stability. The twisted development of the US-ROK alliance and the US-Japan alliance after the end of the Cold War pushed the Korean Peninsula to the brink of a nuclear war instead of denuclearizing it. Even today there is a dangerous coexistence of US-led military alliances and the DPRK's nuclear potential.

Although Beijing and Seoul are moving toward the highest level of security cooperation, Northeast Asia is still far from seeing permanent peace because the US strategy for the reunification of two Koreas involves force, supported by its close allies Japan and the ROK, as opposed to China's peaceful approach based on the stalled Six-Party Talks.

Over the past year chaotic changes have taken place on the Peninsula that have resulted in Washington's declining role in Korean affairs, partly for imposing one sanction after another on Pyongyang which, in turn, has made the latter more determined to conduct nuclear tests.

Apparently, this also has "cooled" relations between Beijing and Pyongyang, and prompted DPRK leader Kim Jong-un to speculatively seek support from Russia and even Japan. Given the reigning chaos in the region, all parties to the Six-Party Talks (the DPRK, the ROK, the US, Japan, Russia and China) should update their ways of thinking and seek a solution that benefits all. In this regard, the China-ROK cooperative spirit will be of immense help.
