The country has been in turmoil since the generals ousted Suu Kyi on February 1, with nearly 850 civilians killed in a brutal crackdown by security forces on near-daily protests against the coup.

The 75-year-old Nobel laureate, who has been in custody since the coup, is facing a raft of wide-ranging criminal charges, including sedition and breaching a colonial-era secrecy law.

The latest charges relate to allegations by the former Yangon region chief minister that Suu Kyi illegally accepted $600,000 in cash from him along with around 11 kilograms of gold.

The Anti-Corruption Commission found evidence that Suu Kyi had committed "corruption using her rank", according to the Global New Light of Myanmar, a state-run newspaper.

"So she was charged under Anti-Corruption Law section 55."

She is also accused of abusing her authority when renting two areas of land for her charitable foundation.

After weeks of legal wrangling, two of Suu Kyi's trials are due to start in earnest next week, hearing evidence from witnesses.

In Naypyidaw, the remote capital purpose built by the previous military regime, her trial will start on Monday on charges of violating restrictions during last year's election campaign and possessing unlicensed walkie-talkies.

A separate case is scheduled to start on June 15, where she is charged with sedition alongside ousted president Win Myint and another senior member of her National League for Democracy (NLD) party.

- Charges 'absurd' -

Her lawyer, Khin Maung Zaw, dismissed the corruption charges as "absurd".

"There is an undeniable political background to keep her out of the scene of the country and to smear her prestige," he told AFP, saying she could face long prison terms on the secrecy and corruption charges.

"That's one of the reasons to charge her -- to keep her out of the scene."

Suu Kyi spent more than 15 years under house arrest during the previous military rule before her 2010 release.

Her international stature diminished following a wave of military violence targeting Buddhist-majority Myanmar's marginalised Muslim Rohingya community that displaced more than a million people, but the coup has returned Suu Kyi to the role of cloistered democracy icon.

The junta has previously said it would hold fresh elections within two years but has also threatened to dissolve the NLD.

"That election -- I cannot say if it will materialise or not, and maybe NLD will not be able to compete," Suu Kyi's lawyer Khin Maung Zaw told AFP.

"But for Aung San Suu Kyi, if she is convicted under these charges she will not be allowed to compete."

Junta leader Min Aung Hlaing has justified his power grab by citing alleged electoral fraud in the November poll, which Suu Kyi's NLD won in a landslide.
