South Korea's chief nuclear envoy is in China for consultations on North Korea's nuclear test plans with the reclusive state's biggest ally.
Lim Sung-nam will meet with his Chinese counterpart, Wu Dawei, today. where he's expected to make a last-ditch diplomatic effort to deter North Korea from further provocations.
Lim is likely to stress that denuclearization of the Korean peninsula is a must for peace and stability in the region, and a third nuclear test by the North will pose a great threat to regional security.
