Myanmar's democratically elected leaders are convicted of inciting the military and violating the country's strict covid restrictions.
Among the accusations leveled against her are illegal imports of walkie-talkies.
Keep away from power
The sentence is 2 years in prison for each of the crimes, a total of four years, according to the junta's spokesperson Zaw Min.
According to Myanmar's constitution, Suu will be disqualified from all higher offices in the future by the prison sentence.
Both her supporters and legal experts believe that the accusations are false and that the purpose of the legal process was to make her return impossible, report4 AP.
The 76-year-old Suu was deposed and placed under house arrest during the military coup in February, which came to overthrow the election victory and prevent her from another term in office.
Her party, the NLD (National Prohibition of Democracy), was accused of, among other things, electoral fraud and dissolved, but according to international observers, the election went correctly.
The popular protests that have been going on in Myanmar since then have been crushed with an iron fist by the military but have nevertheless developed into something that is beginning to resemble civil war.
Questioned democracy fighter
Aung San Suu Kyi was already a human rights activist in Myanmar in the 1980s, and spent long periods under house arrest.
In 1991, she was awarded the Nobel Peace Prize for her peaceful struggle for democracy.
In 2010, she was released and was again able to openly engage in politics.
In the 2015 election, Suu Myanmar (then Burma) became the first democratically appointed president.
In 2017, Suu fell in the esteem of the outside world due to the state involvement in the bloody persecution of Myanmar's Muslim minority Rohingya.
