The average minimum number of black players that must be selected by the Proteas has been announced.
The Proteas will be required to field an average minimum of 54 per cent black players and an average minimum of 18 per cent black African players during the course of a season.
The quotas, which have come into immediate effect, were described as "a natural progression in the board's determination to drive transformation aggressively as part of CSA's policy to make cricket a truly national sport accessible to all."
CSA president Chris Nenzani said: "What is really encouraging is that the … Proteas, who are our flag bearers, are already achieving these targets and in some cases exceeding the targets we have just set.
"With the targets being measured over the full season and being cumulative across all three formats, our selectors and team management will have the flexibility to deal with varying circumstances."
Cricket South Africa has been criticised by the country's sports minister Fikile Mbalula for failing to do more to combat the apartheid legacy of disproportionate white representation among its national teams.
