Tokyo, Sha'ban 9, 1436, May 27, 2015, SPA -- Japan, Republic of Korea and the United States agreed in Seoul on Wednesday to ramp up pressure and sanctions on North Korea amid growing concern of Pyongyang's missile and nuclear programmes, dpa cited a report as saying. The three countries acknowledged that advancement in the North's nuclear capability is "serious" and shared a "sense of urgency" in addressing the problem, Yonhap News agency reported. The first trilateral meeting in four months came as North Korea has refused to return to the negotiating table and instead continued issuing belligerent statements. --SPA 13:05 LOCAL TIME 10:05 GMT www.spa.gov.sa/w
