An estimated $750 million is missing from Angola's treasury [after] a deal with Russia facilitated by a Swiss bank and a shell company registered in Britain's Isle of Man, a report by a corruption watchdog group said. Russian and French arms dealers got away with $263 million, Angola's president reportedly stashed away more than $36 million, and three Angolan officials and a former Russian legislator got away with smaller amounts. Another $400 million is unaccounted for, according to Corruption Watch UK. The Angolan expos is the latest of a slew of reports on corruption, its cost to development, and how it is aided by bankers and shell companies that keep secret the identities of owners. Angola has long been accused of siphoning off payments from its massive oil production, worth about $40 billion in 2011 according to Revenue Watch. They enrich a small coterie surrounding President Jose Eduardo dos Santos, while nearly half the population lives below the poverty line. Dos Santos has ruled Angola for 33 years. The $750 million that disappeared from Angola was supposed to repay a $1.5 billion debt to Russia for help in its 27-year civil war. Angola paid with promissory notes on future oil shipments, but those notes went through shell companies that milked much of the money, the report said. Russian and French arms dealers took most of the money owed to Russia, the report said. The illegal transfer of capital from Africa has surpassed $50 billion a year.
