In response to UN Security Council Resolution 2087 which was approved on Wednesday, North Korea vowed that it will carry out a "high-level" nuclear test. This may not be mere angry words, because South Korea says preparation for North Korea's new nuclear test is already in progress.

Wednesday's UN resolution condemned North Korea's rocket launch in December and expanded existing sanctions. After putting a lot of effort into amendments for the draft resolution, China also voted for it.

It seems that North Korea does not appreciate China's efforts. It criticized China without explicitly naming it in its statement yesterday: "Those big countries, which are obliged to take the lead in building a fair world order, are abandoning without hesitation even elementary principles, under the influence of the US' arbitrary and high-handed practices, and failing to come to their senses."

China has a dilemma: We are further away from the goal of denuclearization of the Korean Peninsula and there's no possible way for us to search for a diplomatic balance between North Korea and South Korea, Japan and the US.

China should be more relaxed and reduce our expectations on the effect of our strategies toward the peninsula. We should have a pragmatic attitude to deal with the problems and pursue the optimal ratio between our investment of resources and strategic gains.

China can neither take one side of the peninsula conflict like the US and Japan nor dream of staying aloof. We should readily accept that China is involved and may offend one side or both sides.

China's role and position are clear when discussing North Korea issue in the UN Security Council. If North Korea engages in further nuclear tests, China will not hesitate to reduce its assistance to North Korea. If the US, Japan and South Korea promote extreme UN sanctions on North Korea, China will resolutely stop them and force them to amend these draft resolutions.

Just let North Korea be "angry." We can't sit by and do nothing just because we are worried it might impact the Sino-North Korean relationship. Just let the US, Japan and South Korea grumble about China. We have no obligation to soothe their feelings.

Due to China's strength, as long as our attitude is resolute, the situation will be gradually influenced by our principles and our insistence.

China is a power adjacent to the Korean Peninsula. This means that our strategic interests are complex and diverse. China should maintain our national interest to the full extent instead of any other side's interests.

China hopes for a stable peninsula, but it's not the end of the world if there's trouble there. This should be the baseline of China's position.

China is doomed to be located in East Asia where the situation is now quite chaotic. But luckily, China is the most powerful among the region's countries, so it will be influenced the least by the situation. China should stay calm.
