South Korea called on Monday for a new push to restart dialogue with North Korea on ending its nuclear arms programme as Washington seeks to increase pressure on Pyongyang with punishment for its atomic and missile tests. North Korea, which tested a nuclear device in May, has quit six-party talks. The on-again-off-again talks involved the two Koreas, host China, Japan, Russia and the United States. South Korea's top nuclear envoy said Seoul and Washington were on the same page on enforcing U.N. Security Council resolutions designed to cut off the North's lucrative arms trade but more needed to be done to bring Pyongyang back to dialogue. "(As) you put it yesterday on the form of two-track approach, we have to think about resumption of dialogue as well," South Korea's Wi Sung-lac told U.S. Assistant Secretary of State Kurt Campbell, who is visiting Seoul. Campbell said at the weekend the United States was ready to hold talks with North Korea if the conditions were right but will also press sanctions to punish Pyongyang for provocative actions. The U.N. Security Council on Thursday expanded the list of North Korean bodies and individuals under sanctions for nuclear and missile activities, adding its atomic energy agency and two of its top officials. Campbell leaves South Korea later on Monday for Phuket, where all the countries of the six-way talks will be represented at a regional security forum.
