South Korea and the U.S. have agreed to deal with the North Korean nuclear issue through both sanctions and pressure, and dialogue.

National Security Adviser Chung Eui-yong and his U.S. counterpart H.R. McMaster met at the White House Thursday and spoke for about 80 minutes.

Participants of the meeting say they discussed ways to create a dialogue opportunity on denuclearization while sanctions and pressure are continuously applied on the North.

The two officials also agreed largely on the details of a bilateral summit including the agenda and date ahead of President Moon Jae-in's visit to the U.S. later this month.

Sources say the summit agenda will include stepping up the alliance, the North Korean nuclear issue, trade, and cooperation on global issues.
