"We are maintaining dialogue on the Customs Union, but we have never set any deadlines by which [Ukraine] should make a decision, or otherwise good bye," Medvedev said at a joint press conference with Ukrainian President Viktor Yanukovych in Donetsk.
Some high-ranking Ukrainian officials have said that "accession to the Customs Union is not on their agenda," Medvedev said. "It would have been better on the agenda for them. But nevertheless, we will see what comes out of these dialogues. We are always open to discussing any issue with our Ukrainian partners," he said.
The Russian president said he had told his Ukrainian counterpart openly that "there can be no accession to the Customs Union, as well as, by the way, to the European Union or any other union, in some special format."
