A joint statement released on Wednesday by Russia's Ministry of Defence, said Russian and Syrian forces had prepared buses to relocate refugees at the camp in the Rukban area and would guarantee them safe passage so they could start new lives, Al-Jazeera reported.
Tens of thousands of Syrian refugees are facing harsh living conditions at the Rukban camp near the Syria-Jordan border, despite Russian attempts to set up "humanitarian corridors" through the region last week.
"We also call on the United States, whose military units are on Syrian territory illegally, to leave the country," the joint statement issued on Wednesday read.
The US said earlier this month it would leave about 400 American troops split between two different regions of Syria, a reversal by US President Donald Trump that could pave the way for Washington allies to keep troops in Syria.
The move to keep a small fraction of the more than 2,000 US forces currently fighting the Islamic State of Iraq and the Levant armed group (ISIL, or ISIS) in Northeastern Syria came amid fierce criticism of Trump's decision in to withdraw all US soldiers in the war-torn country.
Critics have warned against a number of possible outcomes from a sudden withdrawal, including a Turkish attack on Kurdish-led Syrian Democratic Forces (SDF), Washington's main ally in the fight against ISIL, as well as a resurgence of ISIS.
Daesh's presence has been confined to the village of Baghouz in Deir Ezzur. Its fighters are on the brink of defeat, but a future resurgence of the group has become a concern among European states, who refuse to take back foreign fighters.
Trump announced the decision to keep troops in Syria after he spoke by phone to Turkish President Recep Tayyip Erdogan - who wants to set up a safe zone along the Turkey-Syria border.
Erdogan stated that the zone should be cleared of the US-backed Kurdish YPG (People's Protection Units) militia, which Ankara considers a "terrorist" group tied to the outlawed Kurdistan Workers' Party (PKK) inside its own borders.
