Apart from that, the diplomat confirmed that Moscow was hopeful that a next round of Syrian talks in Kazakhstan's capital Astana would take place on July 4-5.
Since a resumption of peace negotiations past year, there have been multiple rounds brokered by the United Nations in Geneva between representatives of Syrian rebels and the government of Syrian President Bashar al-Assad, resulting in scant progress.
In an emailed statement, the office of Staffan de Mistura, the United Nations special envoy for Syria, said he wished to convene a seventh round of Geneva talks in July and further rounds in August and September, Reuters reported.
In Washington, the US State Department welcomed the initiative to reduce tensions and violence in southern Syria. Since May, violence levels have vastly reduced in some of those proposed de-escalation areas, but fighting has continued on major frontline areas including in Deraa city.
Hundreds of thousands of Syrians have been killed since the war began more than six years ago, and the conflict has sparked a region-wide refugee crisis that has affected countries across the world.
Russia says Trump is using 'Cold War rhetoric' on Cuba
Keeping that plan in mind, Obama practically eliminated the Cuba issue in United States relations with its southern neighbors. Obama's détente has already lifted exports and raised hopes for more gains, which they said were now in doubt.
Mistura said that the talks will rely on the progress made in the de-escalation zones' deal, which was internationally backed and went into effect last May.
In May, Russia, Turkey, and Iran agreed to establish four safe zones in Syria, as a result of the Astana ceasefire talks, which were supported by the Damascus regime and opposed by the Syrian opposition delegates.
Activists in rebel-held Daraa city reported several air raids during the morning hours of June 17, mere hours before the implementation of a localized 48-hour ceasefire agreement brokered by Russian, Jordanian, and American diplomatic officials.
The independent London-based Syrian Observatory for Human Rights said the same day that the cease-fire seemed to be holding.
Multiple rounds of Syria peace talks have not yielded much in the way of results.
