North Korea has turned into an unprecedented threat and should be forced to give up all its programs on developing nuclear weapons, Japan's Prime Minister Shinzo Abe told a plenary session of the Eastern Economic Forum in Russia’s Vladivostok.

Axar.az reports citing TASS that, "North Korea has posed a challenge to the international community, turning into an unprecedented, serious and urgent threat," Abe said, recalling that on August 29 Pyongyang launched a ballistic missile that flew over Japan’s territory.

On September 3, North Korea conducted its sixth nuclear test "at a point at the distance just 300 km from here, Vladivostok," and the explosion yield "significantly increased the previous ones."

"North Korea is pursuing the line of escalation of open challenges to the world, prosperity, and world order not only in the region but in the whole world," Abe said.
