LUANDA, Oct 28 (Reuters) - Angola on Wednesday called the conviction of the son of the late French President Francois Mitterrand and others over illegal arms sales to the African country as unjust, biased and politically motivated.

A Paris court on Tuesday convicted Jean-Christophe Mitterrand, former French Interior Minister Charles Pasqua and others of involvement in illegal arms sales to Angola, lifting the lid on a murky world of secret payments linking Paris to one of Africa's longest wars.

Known as "Angolagate", the trial centred on $790 million in Soviet-made arms sales to Angolan President Eduardo dos Santos's MPLA between 1993 and 1998 when it was fighting UNITA rebels, a deal a Paris court said violated United Nations arms embargo.

Angola's government said there was no U.N arms embargo at the time, and the trial was motivated by vengeance because some Angolans backed by the French special services during Angola's 27-year civil war had failed to gain power.

"There was no international embargo against the acquisition of arms by Angola's legitimate government and these were bought by Angola in a perfectly legal business transaction between two sovereign states," the government said in a statement.

"So much so, that none of the deal's signatories were summoned during this judicial process."

ARMS DEALERS

The comments appeared at odds with the evidence produced during five months of court hearings in Paris last year. The arms deals in question were not between the French and Angolan states. Rather, they were brokered by two private arms dealers, Pierre Falcone and Arkady Gaydamak, both of whom were convicted of illegal arms trafficking and sentenced to six years in jail.

Mitterrand was found guilty of taking over $2 million from Falcone and Gaydamak to promote their interests. He was fined and given a suspended two-year jail sentence.
