KYIV, July 10 - Ukraine made a much greater contribution to global security than it received in return, and is unchanged on the path of its Euro-Atlantic aspirations, President Petro Poroshenko said in an article published by the Financial Times.

“In the security policy I will continue to call for strengthening Ukraine's ties with NATO. This is our sovereign choice, and no other country should have the right to veto our ambitions,” Poroshenko wrote.
