A will not directly sell to B's customer. If B voluntarily registers customer C (using C as an example) with A, A will not directly sell to C, but will notify B of C's purchasing information. However, if B does not register any information with A, and customer C purchases from A through other channels, A is not aware that C is B's customer and has the right to sell to C. Or if C becomes a customer of A's other distributors in South Africa later, A is not responsible for coordinating the competition among the various distributors within South Africa.
