"The IMF Executive Board meeting on Ukraine has been postponed to allow the staff time to assess the implications of various recent developments for the program. We expect to announce a new date soon," he said at a briefing in Washington. He did not specify what events were being discussed. "As I have said I don't have a lot for you beyond what I have said. I don't have details of the developments of our staff," he said, asked whether there is a link between the postponement of the meeting date and the trade blockade of parts of Donetsk and Luhansk regions controlled by Russia-backed separatists.
