Nuclear issue tops leaders' agenda in ROK, experts say

Washington and Seoul are expected to renew their call for Pyongyang to go back to the negotiating table during Barack Obama's visit to the Republic of Korea (ROK) today.

In the one-day visit by the United States president to the ROK capital - the last leg of his maiden Asian trip that has taken him to Japan, Singapore and China - Obama will meet with his ROK counterpart Lee Myung-bak.

Denuclearization will be the major topic between Obama and Lee, said Huang Youfu, director of the Institute of Korean Studies at Beijing-based Central University for Nationalities.
