(VOVworld) - Sanctions against North Korea are not enough to make a breakthrough in denuclearization efforts on the Korean peninsula, said China's top nuclear envoy Wu Dawei in a meeting with his South Korean counterpart Kim Hong-kyun in Seoul on Monday.

Wu said during the closed-door meeting that mutual concerns for security should be discussed to make a breakthrough in the denuclearization process. Experts see his remarks as a reaffirmation of China's stance that sanctions and pressure are not enough and talks are necessary to mitigate the North's jitters of its security being threatened by the US.

The US, meanwhile, argues it’s not time for talks and that all options, including military action, remain on the table in dealing with North Korea.
