Belgium Apologise For Mixed-Race Kidnappings In Colonial Era...
The "métis" children born to Belgian settlers and local women were forcibly taken to Belgium and fostered by Catholic orders and other institutions.
About 20,000 children are believed to have been affected.
Most fathers refused to acknowledge the paternity of their children.
The children were born in the 1940s and 1950s and taken to Belgium from 1959 until the independence of each of the three colonies.
Some of the children never received Belgian nationality and remained stateless.
Speaking in the Belgian parliament, Mr Michel said the country had breached the children's basic human rights, seeing them as a threat to the colonial system.
It had, he said, stripped them of their identity, stigmatised them and split up siblings.
"I vow that this solemn moment will represent a further step towards awareness and recognition of this part of our national history," he said in his statement.
Many of the mixed-race children had gone on to help Belgium become a "more open and tolerant society", the prime minister added.
He also expressed Belgian compassion for the "African mothers whose children were snatched from them".
Two years ago, the Catholic Church apologised for its role in the scandal.
Last year, Belgian MPs called on the government to help the affected children find their biological parents and also gain Belgian nationality.
