"I am afraid that the Putin-Trump meeting is overloaded with expectations, which are going to fail … Frankly speaking, I think it is unlikely that after the summit we will witness a U-turn in Moscow’s and Washington’s policy which they have been pursuing over the past several years," he said, stressing that the talks would unlikely lead to the sudden elimination of tensions between Russia and the European Union.
