"In the face of North Korea's increasingly sophisticated nuclear and missile threats, more frequent communications regarding the problem will be very helpful," Kang said late on Monday at the start of a bilateral meeting with her Japanese counterpart Taro Kono in Manila, as quoted by the Yohap news agency.
Kono, in his turn, expressed hope that the countries would cooperate "in a broad range of areas" to build a new era of bilateral relations, the media added.
The ministers met in the Philippines' capital on the sidelines of the ASEAN forum.
In July, North Korea conducted two tests of intercontinental ballistic missiles (ICBMs) in violation of previous UNSC resolutions, with the state-run Korean Central News Agency (KCNA) stating that the second test, carried out on July 28, was successful.
On Saturday, the UN Security Council unanimously adopted Resolution 2371, tightening sanctions against North Korea. In particular, the restrictions target imports of coal, iron ore, lead and seafood imports from the Asian nation to UN member states.
