“The legal process has begun. Court hearings have already started,” he said, adding that Prime Minister Sheikh Hasina had discussed the issue during meetings with her Canadian counterpart.
“We are hopeful,” he said on Wednesday after a programme at the foreign ministry.
The Bangladesh government has been trying to bring him back after the Awami League came to power in 2009.
The foreign minister said they would also bring back all those living abroad who are convicted of crimes, including BNP vice-chairman Tariqe Rahman who was sentenced to life in prison by a Bangladeshi court for his involvement in the Aug 21, 2004 grenade attack.
The grenade was charged an attempt on the life of then leader of the opposition and current Prime Minister Sheikh Hasina.
