Suu Kyi, who was arrested during a coup in February 2021, was found guilty of offences relating to her lease and use of a helicopter while she was Myanmar's de facto leader.
Opponents of the military say the charges against Suu Kyi are aimed at blocking her from ever getting involved in politics again and challenging the military's grip on power.
The latest case centred on accusations that Suu Kyi accepted 11.4 kg of gold and cash payments totalling $600,000 from her protege-turned-accuser, former chief minister of the city of Yangon, Phyo Min Thein.
