With hopes of making the second summit a success,... officials from Pyeongyang and Washington are about to get busy in discussing the details and agenda for the meeting.
Park Hee-jun reports. North Korea and the U.S. are expected to begin their second round of negotiations as early as Thursday,... to discuss the agenda for their upcoming summit.
According to the Washington Post,... U.S. Special Representative for North Korea Stephen Biegun arrived in Hanoi late Wednesday evening.
The report says Biegun will hold talks with his counterpart Kim Hyok-chol,... to clinch a detailed agreement that satisfies President Trump,... and withstands the concerns of hardliners who warn that the North is not to be trusted.

North Korea's special representative for U.S. Affairs of the State Affairs Commission, Kim Hyok-chol also arrived in the Vietnamese capital on the same day after flying via Beijing.
He was accompanied by Kim Song-hye,... head of the unification strategy office at the United Front Department,... and Choe Kang-il,... the acting director-general for the foreign ministry's North American affairs department.

In their first meeting in Pyeongyang earlier this month,... the two sides reportedly discussed the North's shutdown of its Yeongbyeon nuclear complex and Washington's corresponding measures-- setting up a joint liaison office, declaring an end to the Korean War, and the easing of sanctions.
Biegun revealed afterwards that they did set the summit agenda,... but have yet to decide on the details.
With only a week remaining until the second North Korea-U.S. summit,... the two sides are expected to sort out those details,... and lay the groundwork for the Hanoi Declaration to be adopted by Kim Jong-un and President Trump.
