Although South Africa and the Republic of China had diplomatic relations since 1905, only a Chinese Consul-General took up residence in Johannesburg, South Africa. After South Africa became a republic in May 1961, the government of South Africa attempted to set up a consulate in Taipei, Taiwan in 1965. Unfortunately, the Republic of China's government did not accept South Africa's plan to establish its consulate in Taipei. Therefore, the government of South Africa began to take steps to discriminate against the Chinese in South Africa. The purpose of this article is to analyze why the Republic of China's government refused to allow South Africa to establish a new consulate in Taipei, and how the Chinese in South Africa bore and responded to the policy of discrimination taken by the government of South Africa. For example, the Provisions of the Group Areas Act were executed by the government of South Africa, and overseas Chinese were forced to move to designated areas; at the same time, overseas Chinese were not allowed to attend a Chinese dinner-dance to raise money for extensions to a convent school. One of the major reasons which caused the Republic of China's government to bar South Africa's diplomatic delegate from residing in Taipei was the pressure from the United Nations Security Council, which did not treat South Africa as a member of the international community as a result of its racial policy, and the Republic of China's government was attempting to obtain support from the United Nations' members to maintain its position in the United Nations. As to South Africa’s policy of discrimination, it became a critical threat to the future development of the Chinese community in South Africa. Finally, the South African Chinese declared their loyalty to South Africa, and received a response from the Republic of China's government in the form of agreement to a South African consulate in Taipei in the 1980s.
