Suu Kyi's trial in the capital Naypyitaw was closed to the public, and her lawyers were barred from speaking to media.
Aung San Suu Kyi, who was ousted by an army takeover in February last year, could face up to 15 years in prison and a fine if convicted.
The country typically grants an annual amnesty to thousands of prisoners to mark the Buddhist New Year, usually a joyous holiday celebrated in many parts.
She is believed to be the most senior official associated with the military-run administration to be shot since February last year when the army ousted the elected government of Aung San Suu Kyi.
Senior Gen. Min Aung Hlaing said he would not negotiate with “terrorist groups and their supporters for killing innocent people” and threatening peace and security.
It targeted eight members of the shadow National Unity Government, which views itself as the country's legitimate ruling authority, and three prominent activists.
Suu Kyi personally presented Myanmar's arguments at the International Court of Justice when the case was first heard in December 2019 but was ousted as civilian leader in a military coup last year.
Cambodia, the current ASEAN chair, said earlier this month that members of the regional group had failed to reach a consensus on inviting Myanmar Foreign Minister to its meetings.
Min Aung Hlaing in a prepared statement released Saturday acknowledged that the conflicts with the minorities have yet to be resolved, saying that had slowed the country's development.
The Global New Light of Myanmar newspaper reported that Suu Kyi was being charged under the Anti-Corruption Law covering bribery, which carries a maximum prison term of 15 years.
The NLD's Phyo Zeyar Thaw, who was arrested in November, was sentenced to death for offences under the country's Counterterrorism Law.
Suu Kyi was convicted last month on two other charges and given a four-year prison sentence, which was then halved by the head of the military-installed government.
The sentence, passed in a special court inside Yangon's Insein prison, is the latest blow struck in the military authorities' legal campaign against Suu Kyi's National League for Democracy.
Suu Kyi has been attending court hearings in prison clothes — a white top and a brown longyi skirt provided by the authorities.
While more than five million people died from the virus, Myanmar leader Aung San Suu Kyi was arrested in a coup.
