The South African province Gauteng has decided to wind up its motor sport programme.
The Gauteng Motor Sport Company earlier looked into reviving a South African grand prix, and sponsored the Renault and BMW-Sauber teams.
BMW motor sport director Mario Theissen said last year its Gauteng backing was a "long-term" deal.
But executive council member Firoz Cachalia has announced that the province is paying to wind up its contracts within the next two months.
"We're dealing here with a lot of money, a lot of interested parties, and international contracts," he said.
A statement confirmed that the BMW-Sauber deal was "terminated amicably".
