"I wish to speak to the foreign ministers of China and Russia, this is likely to take place in the beginning of the week," Kishida told reporters, adding that Pyongyang's nuclear arsenal poses a threat to the entire world.
"There is a need for a strong signal and strong measures to make the DPRK take constructive steps," he stated.
The telephone talks with Lavrov and Wang could be held as early as Sunday.
