WASHINGTON — The United States said this morning that North Korea has agreed to suspend nuclear activities and a place moratorium on nuclear, and long-range missile tests in a breakthrough in negotiations with the secretive communist nation.

The announcement comes little more than two months after the death of longtime ruler Kim Jong Il, and suggests North Korea has met the key U.S. preconditions for restarting multi-nation disarmament-for-aid talks that the North withdrew from in 2009.

State Department spokeswoman Victoria Nuland said the North has agreed to alllow International Atomic Energy inspectors to verify and monitor the moratorium on uranium enrichment and confirm disablement of its nuclear reactor at Yongbyon.

Her statement says the US will meet with North Korea to finalize details for a proposed package of 240,000 metric tons of food aid.
