Pyongyang said Sunday it had successfully launched into orbit what it claims to be an Earth observation satellite. But the international community views the launch as a disguised test of the reclusive regime's long-range ballistic missile technology, which violates United Nations resolutions. The rocket launch came a month after North Korea conducted its fourth nuclear test.
The U.N. Security Council vowed Monday to "expeditiously adopt a new resolution" for sanctions against the isolated state.
In a telephone conversation Tuesday, Park and Obama "agreed to closely cooperate for the Security Council to adopt a strong and effective resolution on North Korea," Cheong Wa Dae said following the phone call.
The council has been working a resolution since the North's nuclear test on Jan. 6. Sanctions have been placed on Pyongyang for previous tests.
Park stressed the need for "specific measures to be taken under a united international front, so that Pyongyang realizes that its tandem approach to developing nuclear arms and building its economy cannot succeed."
The leaders also agreed on the need for strong measures at bilateral and multilateral levels.
The heads of state also affirmed the U.S.' defense role in South Korea.
It was the second telephone conversation Park and Obama have had since the nuclear test last month.
Park also agreed with Abe on sanctions with Japan. Abe said Japan is preparing its own measures along with the U.N. resolution.
