Hsan Sint was removed from office in June following allegations he misused USD 10,000 to build a pagoda near Naypyitaw.
During his trial at the Detkhina District Court, judges added a sedition charge, saying his actions hurt the nation's pride.
The judge found Hsan Sint guilty of breaching trust and sedition and sentenced him today to 13 years behind bars. His lawyer, Tin Tun, told The Associated Press he would appeal.
