'Time for concrete action' on North Korea: UN chief

UN Secretary-General Antonio Guterres on Wednesday called for concrete action to follow up on North Korea's commitment to close a missile test site with international monitors present.

Guterres welcomed the announcement by North Korean leader Kim Jong Un during a summit with his South Korean counterpart Moon Jae-in in Pyongyang.

"The commitments reflected in the joint statement include important military confidence-building measures and a commitment by the DPRK to dismantle missile engine testing infrastructure in the presence of experts from related countries," Guterres said in a statement.

"Now it is time for concrete action."
