The country's army-dominated interim parliament has voted in the transition plan despite promises to stage elections in February.
Mali's lawmakers have approved a plan allowing the military junta to rule for up to five years despite regional sanctions imposed on the country over delayed elections.
On Monday, 120 members of Mali's 121-seat interim parliament called the National Transitional Council, and took the decision.
The army-dominated legislature also decided that the country's interim president cannot stand for a future democratic election, as part of the same bill. Of the lawmakers attending the vote, none voted against the bill or abstained.
The bill does not mention Mali's Interim President Colonel Assimi Goita by name, leaving open the possibility that he could run if he steps down ahead of a future election. Nor does the bill mention on what date a future election might be held.
Goita has pledged to restore civilian rule, but he has refused to commit to a date.
The Economic Community of West African States (ECOWAS) has stated that its mediator for Mali, former Nigerian president Goodluck Jonathan, will visit the capital Bamako on Thursday.
After staging a coup in the impoverished Sahel state in August 2020, Mali's military rulers initially promised to stage a vote in February 2022.
But in December last year, the junta proposed staying in power for between six months and five years, citing security concerns.
In response, ECOWAS last month imposed a trade embargo and closed its borders with Mali. The bloc has called the potential length of the transition unacceptable.
Tensions with the junta contributed to France's announcement last week that it was withdrawing its troops from Mali which are deployed under the Barkhane force in the Sahel.
The landlocked nation of 21 million people has struggled to contain a brutal militant attacks that emerged in 2012, before spreading three years later to neighbouring Burkina Faso and Niger.
Across the region, thousands of soldiers and civilians have been killed and two million people have been displaced by the conflict, of which Mali remains the epicentre.
