KIEV, July 26 – The fifth meeting of the Russian-Ukrainian Interstate Commission, chaired by the presidents of Russia and Ukraine, Viktor Yanukovych and Dmitry Medvedev, is likely to take place this autumn, a source in diplomatic circles told Interfax-Ukraine.

"There haven't been any preparations for this meeting yet, which means it will not take place in July. As for August, it is a holiday season, therefore, the meeting is likely to be held in the fall," he told the agency.
