If we’re optimistic about the outcomes from last week’s monumental inter-Korean summit, the positive overtures North Korean leader Kim Jong-un seems to be making bode well for the Korean Peninsula. In anticipation of the upcoming Trump-Kim summit, American negotiators should note that being a bit more cautious with expectations and drawing lessons from past Korean negotiating behavior could lead to lasting change on the peninsula.

The Trump administration’s aggressive nuclear posture will deal a blow to nuclear non-proliferation.

Irresponsible unilateral scrapping of the agreement will turn years of international cooperation into dust and ashes.

It’s commonly acknowledged that North Korea won’t give up its nuclear weapon program anytime soon, so there’s no use being unhappy about it. It is also unhelpful to regret past opportunities to stop the program

China and the U.S. have cooperated well on the North Korean nuclear issue. But recent U.S. actions puts this cooperation at risk.

To follow a common security approach that recognizes the interrelations and interdependencies between countries, Washington must step back and reassess the moral and practical implications of its foreign-policy commandment “Do as I say, Not as I do” when it comes to nuclear weapons.

Changing the goal from denuclearization to resuming talks is something worth trying, since other options are becoming dead ends or getting increasingly risky.

The proposal from Beijing and Moscow could push the Korea nuclear crisis out of its dead-end. Yet there is a very long way to go for that to happen, considering the deep-rooted mutual prejudices, suspicions and the extreme lack of strategic trust.

Despite China’s best efforts as an intermediary, Pyongyang has obviously stood on the wrong side of history, against the will of the rest of the world by refusing peaceful engagement. But the six-party talks platform has not been built easily, and it remains the key to meaningful progress.

The Korean nuclear issue is the most complicated and uncertain factor for Northeast Asian security. It has now become the focus of attention in the Asia Pacific and even the world at large. Now, as the issue continues to heat up, one frequently raised question is: Why can’t China take greater responsibility and make North Korea stop its nuclear weapons program?
