When Glyn Davies, the the U.S. special representative for North Korean policy, left Beijing last week after two days of talks with North Korean envoys, he would only say their discussions produced "a little bit of progress" but refused to call it a breakthrough. Today we can see what he meant. The U.S. State Department announced that North Korea has agreed to implement a moratorium on long-range missile launches, nuclear tests and nuclear activities, including uranium enrichment, at its Yongbyon reactor. It will also allow the return of IAEA inspectors to verify the moratorium at Yongbyon. Under the deal the U.S. would provide 240,000 metric tons of food, with the possibility of more later. "The United States still has profound concerns regarding North Korean behavior across a wide range of areas, but today's announcement reflects important, if limited, progress in addressing some of these," said State Department Spokesperson Victoria Nuland. Secretary of State Hillary Clinton called the announcement "a modest first step in the right direction," adding that the U.S. "will be watching closely and judging North Korea's new leaders by their actions."
