Yes, the Bank of China has a branch in South Africa. I remember that the newly opened branch should be China Bank Durban Branch.

Durban Branch is located in KwaZulu-Riche Fond Circle, office area of Umhlanga ridge side, a new financial and commercial district in Durban, natal province.

At present, the Bank of China has set up institutions in Johannesburg and Durban, Lusaka and Kitwe, Luanda and Nairobi, and institutions in Mauritius and Morocco are also in preparation, basically forming a comprehensive coverage of financial services in Africa.
