North Korea agreed Monday to stop building nuclear weapons and allow international inspections in exchange for energy aid, economic cooperation and security assurances, a breakthrough that marked a first step toward disarmament after two years of six-nation talks.

The chief U.S. envoy to the talks praised the development as a "win-win situation" and "good agreement for all of us." But he promptly urged Pyongyang to make good on its promises by ending operations at its main nuclear facility at Yongbyon.

"What is the purpose of operating it at this point?" said U.S. Assistant Secretary of State Christopher Hill. "The time to turn it off would be about now."

Despite the deal's potential to help significantly ease friction between the North and the United States after years of false starts and setbacks, Hill remained cautious.

"We have to see what comes in the days and weeks ahead," he said.
