Prime Minister Shinzo Abe and South Korean President Moon Jae-in agreed Thursday to exert stronger pressure on North Korea, including tougher U.N. sanctions, in the wake of a recent nuclear test by Pyongyang.

The leaders, meeting in Vladivostok, Russia, also agreed on coordinating bilaterally and with the United States, to call on China and Russia to rein in Pyongyang, according to a Japanese official who was at the talks.

"There is a need to take steps toward applying pressure of a different dimension. Security and defense cooperation between Japan, the United States and South Korea are important to enhance deterrence and response capabilities," Abe told Moon, according to the official.
