Financial Times says that China insisted on Tuesday that new UN sanctions against North Korea agreed were not aimed at destabilising the country, as it aired its growing concerns over the "explosive" situation in its communist neighbour. In comments clearly aimed at the US, Wang Yi, foreign minister, used tough language to describe Beijing's fears as he warned of the consequences of provoking unrest. "China will not sit by and watch if there is fundamental destruction of stability on the Korean peninsula," said Mr Wang at a briefing held during the National People's Congress, the annual meeting of the country's rubber-stamp legislature. "China will not sit by and watch unwarranted damage to China's security interests," he added, urging all parties to "act with reason and care, and refrain from aggravating tensions". The unusually blunt Chinese remarks included "language that they use when their bottom line is pretty close to being reached", said Bonnie Glaser, a China expert at the Center for Strategic and International Studies in Washington.
