Ukraine's actions towards Russia are legal - Yatseniuk

Ukraine will influence Russia using legal methods, Ukrainian Prime Minister Arseniy Yatseniuk said.

"Our actions are legal," Yatseniuk said at the 8th Kyiv forum on security on Thursday, responding to a question as to why the property of Russian companies is not being nationalized in Ukraine in response to Russia's actions on the enterprises in Crimea.

He recalled that the Ukrainian government has already filed several lawsuits with international courts and has imposed a number of economic sanctions on Russia. "Everything that is in the international arsenal, everything that we have - it's all being used," Yatseniuk said.
