The Council of Ministers approved on Tuesday the revision of the decree, which creates the Kimberley Process Management Unit, Precious Metals and Gems.
The Kimberley Process is a joint initiative by governments, the diamond industry and civil society to stem the flow of rough diamonds from war or conflict into the international market.
In 2016, a team was in the country after Mozambique expressed its intention to join the Kimberley process.
Government spokesman Filimão Suaze assured that since that time, Mozambique has taken a series of steps in the legislative and procedural field.
"In September of this year the team is supposed to come back here to gauge the degree of compliance with a number of requirements and recommendations made in 2016 and I must assure you that we are on a very advanced path to be very highly rated," he said.
