China's foreign minister on Sunday called on all relevant countries to exercise calm and restraint on the Korean Peninsula, warning of "another delicate period" in the region. 

"The situation on the Korean Peninsula is entering another delicate period," Foreign Minister Wang Yi told a press conference on the sidelines of an annual meeting of China's rubber-stamp parliament.

Wang did not specify reasons for such an atmosphere in the region, but the remarks follow threats from North Korea on protests against ongoing joint military drills between South Korea and the United States.

Wang reiterated China's stance on the North Korean nuclear issue, saying all sides should make joint efforts for an early resumption of the six-party talks aimed at persuading North Korea to give up its nuclear weapons ambition. (Yonhap)
