U.S. special representative for North Korea policy Stephen Bosworth has said that the six-way talks are still a useful tool in fostering denuclearization.

A source who attended the fifth Seoul-Washington Forum held in Washington said Bosworth said the six-way nuclear talks won’t yield immediate results but are useful if used gradually.

On whether to provide food aid to North Korea, Bosworth reportedly said that he believes a U.S. decision on the issue is still pending due to lack of assurance in the monitoring process over food distribution.
