MOSCOW. Jan 24 (Interfax) - The world should tighten political pressure on Pyongyang, Federation Council Defense and Security Committee Chairman Viktor Ozerov told Interfax on Thursday.
"Pressure must be all-inclusive for cooling down nuclear ambitions of Pyongyang and forcing its administration to negotiate," he said.
Both the sextet and the United Nations should put pressure on North Korea, Ozerov said.
He added there was no proof of the North Korean ability to build missiles with warheads. "Yet this is a possible scenario. Through the long years of economic sanctions, Pyongyang has been making such statements to display the scale of its plans and to prove to its citizens and the whole world that it is a great nuclear power," Ozerov said.
The North Korean nuclear test "is a severe blow to international efforts of strengthening the Nuclear Non-Proliferation Treaty, which undermines the international norm of the Comprehensive Nuclear Test Ban Treaty," he said.
