US Undersecretary of State for Political Affairs Nicholas Burns and Under Secretary of State for Arms Control and Security Robert Joseph will leave for Japan, South Korea and China this weekend to discuss resuming the six-party talks.

"They're going to look for ways to make sure that when we do go back to the table in the six-party talks that the talks really do aim at implementing the agreement that was signed in September of 2005, and that we don't just go back to talk, that we go back for concrete action," Rice said in an interview with US media, referring the trip of Burns and Joseph.

The United States has said it wants the six-party talks to be resumed can achieve some positive and concrete results.

The UN Security Council unanimously adopted a resolution in October on the nuclear test conducted by the DPRK.

The resolution, cosponsored by the United States and eight other nations, condemned the nuclear test proclaimed by the DPRK, demanded that the DPRK eliminate its nuclear weapons and nuclear programs in a complete, verifiable and irreversible manner, and imposed sanctions on the DPRK in spheres related to its nuclear, ballistic missiles and weapons of mass destruction.
