Countries’ leaders agreed 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.
They also agreed to seek a stronger United Nations Security Council sanctions resolution against the reclusive regime.
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.
As it was reported earlier President of the United States Donald Trump said that the North Korean nuclear program is "hostile and dangerous for the United States," noting the impossibility of settling the situation on the Korean Peninsula using talks.
