Windhoek, June 12 (IANS): Mojanku Gumbi, advisor to former South African President Thabo Mbeki, said about $90 billion may be illegally taken out of Africa every year.

Gumbi argued the value represented almost 1.5 times of what the continent received in foreign direct investment every year, Xinhua reported.

The capital flight is in forms of the proceeds of crime, tax evasion and corruption, said Gumbi, who revealed this ahead of the African, Caribbean and Pacific countries and European Union Joint Parliamentary Assembly that opens on Monday.

"The fraudulent misinvoicing of trade transactions was revealed to be the largest component of illicit financial flows from developing countries, accounting for 83.4 per cent," Gumbi said, adding the Sub-Saharan Africa region is the worst affected around the world by illicit cash flows.

To solve this problem, Gumbi proposed the adoption of the anti- money laundering as recommended by the Financial Action Task Force.
