"The parties are trying to agree on two documents. It should not be longer than two hours," the official said.
It is expected that a document will be signed for the settlement of the Ukraine problem, which consists of more than a dozen points.
A diplomatic source close to the talks told Tass that "it does not matter how this document is referred to - a declaration or a statement, but it is assumed that some specific actions to resolve the situation will be listed there, about 12 or 13 points."
The negotiations on the Ukrainian issue include German Chancellor Angela Merkel and the presidents of Russia, Ukraine and France - Vladimir Putin, Petro Poroshenko and Francois Hollande, and had been going on for almost twelve hours.
