Burundi's new president, former rebel leader Pierre Nkurunziza, has formed the country's first government since the end of the 12-year civil war.
Mr Nkurunziza has vowed to engage the FNL rebel group in peace talks
He gave key posts to members of his Hutu FDD party, and seven out of 20 ministerial posts to women.
On Monday, parliament approved his nomination of a Hutu woman and a Tutsi man as his deputies.
The new constitution guarantees a balance of power between Burundi's Hutu majority and Tutsi minority.
These stipulations were agreed as part of five-year peace process designed to end the conflict between Hutu rebels and an army led by the Tutsi minority.
1993: Conflict began
Tutsis: 14% of the population
In terms of the agreement, the cabinet should comprise 60% Hutu and 40% Tutsi, with at least 30% of posts going to women.
For much of the time since independence in 1961, control of the state has been in the hands of a narrow Tutsi elite.
There is one rebel group, the National Liberation Forces (FNL), which remains outside of the peace process.
Mr Nkurunziza has told the BBC that the constitution may be changed to allow the FNL to join the government.
On the eve of his inauguration last week, Mr Nkurunziza vowed to engage the FNL in peace talks.
Some 300,000 people were killed in the civil war which was sparked in 1993 by the assassination of Burundi's first Hutu head of state and democratically elected president, Melchior Ndadaye.
