The United States support Kyiv's position that Ukraine's sovereignty over Donbas should be reinstated in 2016, Ukrainian President Petro Poroshenko has said.

"I stressed at a press conference on January 14 that the task I have put before myself and Ukraine, which we are coordinating with our partners, is that Ukraine's sovereignty should be reinstated in Donbas in 2016. The only way to do this is to implement the Minsk agreements," the president said in an interview with Ukrainian TV channels broadcast on Sunday evening.

He recalled that he held talks with U.S. Vice President Joe Biden and U.S. Secretary of State John Kerry during his visit to the World Economic Forum in Davos. "This position was backed by U.S. Secretary of State John Kerry. We had very long negotiations in Davos. A meeting with Biden, which was expected to last 25 minutes, went on for more than four 4 hours," Poroshenko said.

According to him, the parties worked out in detail all the steps for cooperation in this area. "For the first time, we went into details of each clause of the Minsk agreements: what the political settlement means, what the security component is, how we coordinate our actions with our European partners," the head of state said.

Also, he said they discussed reforms in Ukraine and their support by the United States. "There was a statement by the U.S. secretary of state that they hope that as the result of the full implementation of the Minsk agreements, the sanctions against Russia may be loosened," Poroshenko said.
