The U.S. government says it is not in contact with North Korea over the communist country's imminent rocket launch.

Gordon Duguid, acting deputy spokesman for the U.S. State Department, told a news briefing that the U.S. is conveying its dissatisfaction with the launch plans through consultations with other members of the six-way nuclear talks.

The department said U.S. special envoy on North Korea Stephen Bosworth and chief U.S. delegate to the six-party talks Sung Kim are devising countermeasures to the North Korean rocket launch, which will soon be reported to Secretary of State Hillary Clinton.
