South Korean President Moon Jae-in and Japanese Prime Minister Shinzo Abe agreed Monday to pursue "much tougher and more substantive" measures against North Korea in the wake of its successful nuclear test a day earlier,
the presidential office said.
The leaders of the two neighboring states made the decision during their 20-minute phone conversation held earlier in the day to discuss ways to respond to Pyongyang's latest nuclear test, according to Cheong Wa Dae.
They also agreed to seek a stronger United Nations Security Council sanctions resolution against the reclusive regime, it said.

The call came a day after the North carried out its sixth and most powerful nuclear test on Sunday. Pyongyang claimed it successfully tested a hydrogen bomb mountable on an intercontinental ballistic missile (ICBM) capable of reaching the United States. (Yonhap)
