An interim chief of South Korea's main opposition party said Wednesday that Seoul should cooperate with the international community to resolve the North Korean nuclear issue.

Kim Chong-in, head of the Minjoo Party of Korea, made the call, saying there is no other choice than to join hands with the rest of the world to enforce the U.N. Security Council Resolution.

"Not only South Korea but the entire world is pressuring (North Korea)," Kim said during a forum hosted by the Kwanhun Club, an association of senior journalists.

The resolution, adopted earlier this month to punish North Korea for its recent nuclear and missile tests, calls for the mandatory inspection of all cargo going into and out of the North and a ban on the country's exports of coal and other mineral resources, among other things.

Kim, however, said that the government should consider various dialogue formats since the shutdown of a joint industrial park means that the only channel for inter-Korean cooperation has been cut off.

On Feb. 10, Seoul shut down the Kaesong Industrial Complex in the North's border city of the same name in the wake of heightened cross-border tensions. (Yonhap)
