The United States and North Korea have held a third one-on-one meeting as they seek to narrow still wide differences on how to dismantle Pyongyang's nuclear program.

U.S. officials say U.S. Assistant Secretary of State Christopher Hill and North Korean Vice Foreign Minister Kim Kye-gwan met for two hours Thursday in Beijing, on the sidelines of the six-nation negotiations being hosted by China. There was no immediate word on how the talks went or what was discussed.

Wednesday the United States and North Korea each said the other must make the first move to denuclearize the Korean peninsula.

The six-nation talks include the two Koreas, the United States, China, Japan and Russia.
