"The unstable position of the negotiators in Astana is due to the fact that everyone is waiting for the results of the meeting of Vladimir Putin and Donald Trump in Hamburg," Dzhabarov said.
The senator stressed that, as already announced, Putin and Trump would discuss the issue of Syrian settlement, and there may be new agreements between Russia and the United States that the participants of the Astana talks are waiting for.
"At the next stage of the talks in Astana in August, progress can be more noticeable," he added.
The first deputy chairman of the State Duma Committee on International Affairs, Dmitry Novikov, said that the talks in Astana have a solid basis for settling the crisis in Syria.
The meeting of Putin and Trump is scheduled for July 7 on the sidelines of the G20 summit in Hamburg. The next round of negotiations on Syria in Astana will take place in the last week of August.
