国际英语资讯:Possible second Kim-Trump summit brings opportunity, challenge -- U.S. experts

"It (Kim-Moon meeting) is an opening that I hope Washington will use toward a constructive end," Yun, once serving as deputy assistant secretary for Korea and Japan at the U.S. State Department, told reporters at a conference call on Friday.

Yun also believed that Moon, who had spent hours with Kim during his stay in Pyongyang, could update Trump on where Kim wants to go on the whole project.

Despite the positive atmosphere generated from the Moon-Kim summit, challenges still remain before achieving the goal of denuclearization on the Korean Peninsula, said experts.

The United States so far has largely ignored the DPRK's request in the Pyongyang Declaration for "corresponding measures" as the precondition for its further actions on denuclearization, such as the permanent destruction of its main Yongbyon nuclear facility.

The DPRK asked for a peace declaration before any serious progress on denuclearization, while the United States demands the progress should come first, said experts on Korean issues at the Center for Strategic and International Studies (CSIS), a Washington-based think tank.

Moon has reportedly encouraged the idea that Washington could consider a formal declaration to end the 1950-1953 Korean war. But some believed that it may arouse concerns on the U.S. side as the peace treaty may damage the justification for the United States to keep its 30,000 troops in South Korea.

Pyongyang and Washington also diverged on the definition of denuclearization with the DPRK eyeing the withdrawal of the U.S. nuclear umbrella over South Korea and Japan while the United States focusing on the DPRK's weapon program, noted Victor Cha, a senior adviser at the CSIS in an article co-written with his colleagues.
