The U.S. envoy for North Korea policy, Stephen Bosworth, met South Korea's Foreign Minister Kim Sung-Hwan in Seoul before heading to China. Consultations are likely to focus on whether to restart disarmament-for-aid talks involving the United States, the Koreas, Japan, China and Russia. Bosworth will arrive in China later on Wednesday, and be in Japan on Thursday. Speaking after his meeting with Bosworth, South Korea's foreign minister sounded a cautious note about whether the six-party talks could restart, calling them a "useful negotiating tool" for disarming North Korea. "But the right conditions, including North-South dialogue are needed for there to be real progress," Kim Sung-Hwan was quoted as saying by news agency Yonhap. "It depends on the North's behaviour whether it will choose path of conflict or peace."
