The Russian Defense Ministry made the announcement on Tuesday.
The returnees had initially left the Damascus suburb using four humanitarian corridors set up to enable their safe exit from the area.
Militants had been using the area to launch incessant rocket attacks on the capital. Backed by Russian airpower, the Syrian army has been trying to liberate the countryside to both spare the capital from the attacks and liberate thousands of other trapped civilians, whom militants have been using as human shields.
Eastern Ghouta has now been almost fully liberated with the exception of the town of Douma.
Recently, Moscow brokered an agreement between the militants based there and the government, enabling the formers safe exit to Jarabulus, a militant-held town in northern Syria.

It said that 2,269 militants and their families had left Douma since the introduction of the deal.
On Monday, Syrian paper al-Watan said it was a matter of hours before Douma is declared a town empty of terrorism.
Moscow has been demanding that foreign governments stop funneling arms and money to the militants and instead join efforts aimed at ending the foreign-backed militancy in Syria which began in 2011.
