Washington's top North Korea negotiator arrived in China Wednesday for regional talks on resolving a deadlock over a disputed inventory of the North's nuclear programs. US Assistant Secretary of State Christopher Hill was scheduled to meet with his Chinese counterpart Wu Dawei, along with top negotiators from South Korea and Japan. China is the host of multinational talks on North Korea's nuclear program grouping those five nations and Russia. "I believe all parties will use this opportunity to fully discuss the current situation and the next stage work and exchange in depth views on that," Chinese Foreign Ministry spokeswoman Jiang Yu told reporters at a regularly scheduled news conference on Tuesday. Speaking to reporters in Singapore, Hill said he and North Korean Vice Foreign Minister Kim Kye Gwan had "a full discussion on all issues" during a meeting in the Southeast Asian city state.
