The United States and North Korea started talks in Geneva on Monday designed at resuming deadlocked nuclear negotiations, the Yonhap news agency reported.
Six-party negotiations involving both Koreas, China, Russia, Japan and the United States broke down in April 2009, when Pyongyang pulled out.
The discussions are to last for two days and are a second direct meeting between the U.S. and North Korea in the past three months.
The United States wants Pyongyang to commit itself to disarmament before the negotiations are resumed, while North Korea wants no preconditions.
