The People for Achieving Peace and Reunification in a news conference in Seoul on Jan. 14 accused the U.S. defense secretary of trying to let south Korea take part in the U.S.-led missile shield for alleged "cooperation".

He visited Seoul at a time when remarks hostile to the DPRK are heard from those for the U.S. diplomacy and security, said the organization.

The U.S. policy for military pressure on the DPRK rather than dialogue and negotiations will result in escalating tensions on the Korean Peninsula, it said.

It urged the U.S. to unconditionally come out to the negotiating table for peace agreement.
