The European Commission President, Jose Manuel Barroso, warned the Russian President, Vladimir Putin, against a possible Russian military intervention in Ukraine during a telephone conversation, as the Commission said.
In a press release issued, it's noted that Barroso "expressed concerns about the concentration of Russian troops in the Ukrainian border" and "warned against any unilateral military action in Ukraine, under any pretext, including humanitarian".
He supported the position adopted this weekend by the American President Barack Obama, the British Prime Minister David Cameron and the German Chancellor Angela Merkel.
The European official also spoke on the phone with the President of Ukraine Petro Poroshenko, as noted in the statement.
During the two telephone conversations, the president of the European Commission expressed concerns of the European Union for the humanitarian impact of the conflict in eastern Ukraine and appealed for respect of international humanitarian law.
Barroso, according to the Commission, is expected this week to take an urgent decision to offer additional humanitarian assistance in the context of United Nations' contribution to international aid project.
From his part, the Russian President said that Russia cooperates with the International Committee of the Red Cross to send humanitarian aid to Ukraine.
"It was stressed that the Russian side, in cooperation with representatives of the International Committee of the Red Cross, sends convoy to Ukraine" Kremlin said in a press release about the telephone conversation between the two men.
No details were given from Kremlin on the date of this mission, the content or even the origin of this "humanitarian convoy".
The Western countries have strongly rejected the idea of a Russian humanitarian mission, while accusing Moscow that it feeds the insurgency in Ukraine providing weapons and fear for an operation that will take place under the guise of a mission to help their citizens.
Russia, however, agreed with Kiev for the Red Cross to carry out a humanitarian mission in eastern Ukraine and hopes that "Westerners won't raise obstacles" said the Russian Foreign Minister Sergey Lavrov.
"I hope that in the near future, this humanitarian action will take place under the auspices of the International Committee of the Red Cross. We have agreed with the Ukrainian government for all the details" emphasized the Minister, as reported by the news agency RIA Novosti.
