JAKARTA, Oct 20, Reuter - Indonesia's President Suharto on Saturday gave 10 million dollars to South Africa's anti-racist African National Congress, ANC leader Nelson Mandela said.

"It is my pleasure to tell you...the president has granted us a donation of 10 million dollars," Mandela told a foreign affairs forum during his four-day visit to Indonesia.

"This donation...guarantees our final victory. We will leave this country knowing that the days of oppression are numbered. This donation is the writing on the wall for those who once believed they would rule South Africa for centuries," he said.

Though violently anti-communist, Indonesia has long supported the leftwing ANC in its struggle to end racial segregation in South Africa. Suharto told Mandela at a banquet on Friday night that Indonesia looked to him as the future leader of South Africa.

Secretary of State Murdiono earlier told reporters Indonesia had also committed 250,000 dollars a year for three years in aid to the frontline states surrounding South Africa.

Mandela told Saturday's forum he was convinced President F.W. de Klerk, with whom the ANC has been holding talks, was genuine in his desire to dimantle apartheid but the measures he had taken did not go far enough.

"Mr de Klerk is serious in his declaration that he wants fundamental change and he wants fundamental change soon," the black leader said. "He has already taken very interesting measures to scrap apartheid.

"But while of course from the white man's point of view these changes are very important, for us they are not so important. The demand is for...one person one vote...and we are still very far from that."

Mandela said de Klerk's National Party suggested it did not intend to give every South African an effective vote by saying whites must retain the right to decide whether a parliament's decision was in their interests or not.

"That means...that in spite of the extension of the vote to everybody, the whites will still have the right of veto. We reject that. We say that apartheid cannot be destroyed by preserving apartheid," he said.

Mandela was warmly received by an audience that included Indonesians who fought for independence from Dutch colonial rule 45 years ago.
