"When in the 1990ies Ukraine voluntarily dismantled the world’s third largest nuclear arsenal, we did so being convinced in supremacy of such fundamental international principles as inviolability of international borders and states’ territorial integrity and sovereignty.

"The international community has collective responsibility to restore respect for international law and to find lasting solutions to the most urgent threats to global peace and security. It is therefore the ultimate responsibility of the Security Council to spare no effort in order to achieve this overarching goal and to prove that non-proliferation system effectively works.

It is the preparation for the real elections, which must be arranged by Ukraine, of course, with the support of the world community, rather than manipulative Russia," Klimkin said.
