South Korea has said it will withhold food and fertilizer shipments to impoverished North Korea until the missile crisis is resolved, even as it pledged to hold high-level talks with the communist regime next week. Meanwhile, a draft UN resolution on sanctions against Pyongyang could be put to a vote Saturday, as regional powers moved to coordinate their response to North Korea's test-firing of seven missiles. US Assistant Secretary of State Christopher Hill, dispatched to Northeast Asia in the wake of the missile barrage, was in Seoul on Saturday for talks with Chun Young-woo, South Korea's top negotiator in nuclear talks. After talks with Chinese officials in Beijing on Friday, Hill said the Chinese, the North's top allies, were displeased by the missile tests. "They were very clear in their views of the North Korean missile launches, very clear that they have no interest in seeing this happen and do not regard this in any way positively," Hill said. He was expected to travel from South Korea to Japan on Sunday.
