The ministry's spokeswoman, Elena Samkharadze, said on July 30 that the monument in Gori will be restored by December 21, Stalin's birthdate.
The monument was torn down amid a crackdown on Soviet-era monuments by pro-Western President Mikheil Saakashvili in 2010.
Saakashvili's presidential term does not end until October, but his authority has been further weakened by a constitutional reform that has shifted powers from the presidency to parliament and new Prime Minister Bidzina Ivanishvili.
Speaking on July 30, Saakashvili said the move is anti-Georgian and barbaric and he is "outraged with it."
The 6-meter bronze monument to Stalin is currently lying on the ground at a Georgian Defense Ministry military base in Gori.
A spokesperson for the ministry told reporters that the statue will not be returned to its original pedestal in Gori's central square but will be erected at the town's Stalin Museum.
