The South Korean government yesterday urged the Democratic People's Republic of Korea (DPRK) to faithfully implement its pledge to disable its nuclear facilities and present a full list of its nuclear programs.

South Korea and the United States shared the view that a summit between South Korea, the DPRK, China and the US will be realized only after a "satisfactory" settlement of the DPRK nuclear issue, said Baek Jong-chun, who is a senior aide to South Korean President Roh Moo-hyun.

"There was a common understanding that if the North (DPRK) disables its nuclear facilities and completely declares its stockpile, we could pursue the four-way summit at an appropriate time," said Baek, who met with US Secretary of State Condoleezza Rice and National Security Adviser Stephen Hadley during his recent three-day visit to the United States.

In early October, Roh conducted a three-day visit to Pyongyang and reached an agreement with top DPRK leader Kim Jong-il on a three or four party summit to discuss a peace regime on the Korean Peninsula.

But Roh said in mid-October that the summit will be held among four nations.
