Washington last week resorted to "Shuttle diplomacy" and clearly identified the desire to increase its role in the settlement of the Ukrainian drop, says American intelligence analysis center.

Center dimension emphasize that U.S. officials met with Prime Minister of Ukraine Arseniy Yatsenyuk and Ukrainian President Petro Poroshenko and the commissioners of the Russian side.

according to experts of Stratfor, the recent visit of the assistant United States Secretary of state Victoria Nuland in the Russian Federation is evidence that the White house's position in the Ukrainian conflict becomes more flexible. Visits by Kerry and Nuland signal about the fact that Washington wants to become a more important stakeholder dialogue on the Ukrainian crisis and is willing to discuss compromise solutions with the participants of the " channel four ".

Russian negotiators want to achieve from the capital of the USA several key concessions, Analysts say. First, Moscow is concerned about the presence of American military trainers to Ukraine and expects the United States guarantees that " the Ukrainian mission of the U.S. military as long as six months will not be renewed or extended. Another key requirement of the Kremlin is the clotting activity of the United States and NATO on the Eastern borders of the Commonwealth - in the Baltic States, Poland, Romania and Bulgaria.

"The US may not want to go for a consensus on the mission, military trainers to Ukraine, but the White house can defend itself provide weapons to Kiev, which would have increased the military capacity of Ukraine, if the situation reaches this point," emphasizes Stratfor.
