U.S. lawmakers adopted a resolution on Monday, demanding the Democratic People's Republic of Korea (DPRK) immediately stop its "hostile rhetoric" toward the Republic of Korea (ROK) and give up its nuclear program on the eve of a U.S.-ROK summit meeting.

The DPRK should "immediately stop any hostile rhetoric and activity towards the Republic of Korea and engage in mutual dialogue to enhance inter-Korean relations," the House of Representatives said in the resolution.

The lawmakers also urged Pyongyang, which conducted an underground nuclear test late last month, to comply with UN resolutions and all official documents approved by the six-party talks seeking an end to the DPRK's nuclear program.

The six-party talks, involving the DPRK, the United States, China, the ROK, Japan and Russia, was first held in Beijing, China in August 2003, and has made tangible progress on the issue in the following years.

The DPRK destroyed the cooling tower at its Yongbyon nuclear complex in June last year, marking a symbolic step ahead toward the goal.

However, the DPRK vowed on Saturday to build more nuclear weapons and to start enriching uranium for a new atomic weapons program following the UN Security Council's unanimous vote on Friday to impose tougher sanctions for Pyongyang's recent nuclear test.
