With the end of the war, the government of Transvaal Province decided to bring in Chinese laborers with the help of British connections with the Chinese government. Thus in May 1904 a protocol was signed between the British Foreign Office and the Chinese Minister to Great Britain, Chang Te-i, in which it was agreed to transport Chinese laborers in return for adequate guarantees for their safety.
戰爭結束後，杜省政府決定引進中國勞工，於是透過英國政府與中國交涉，在一九○四年（清光緒卅年）五月三日，雙方簽訂「保工章程」，中國同意輸出華工，並要求對華工提供應有的保障。
