Secretary of State Condoleezza Rice intends to confer on implementation of U.N. sanctions against North Korea in a trip next week to Japan, South Korea and China.

"She will talk about what goes afterward," and other governments also may join in the discussions, State Department spokesman Sean McCormack said in announcing Rice's trip.

She intends to take off for Tokyo next Tuesday and return Oct. 22, although McCormack said there could be other stops added along the way.

One possibility is Russia, another key player in carrying out sanctions on North Korea that McCormack said might be approved as early as Saturday.
