Since this time, the mission has worked in Russia and the Gold Coast (Ghana) from 1828, India from 1834, China from 1847, Cameroon from 1886, Borneo from 1921, Nigeria from 1951, and Latin America and the Sudan from 1972 and 1973.

[3] On 21 March 1832, a second group of missionaries including Andreas Riis, Peter Peterson Jäger, and Christian Heinze, the first mission doctor, arrived on the Gold Coast only to discover that Henke had died four months earlier.

[5] In West Africa, the Basel Mission had a small budget and depended on child labour for many routine operations such as daily household chores.

The children were pupils in the mission schools who split their time between general education, religious studies, and unpaid labour.

The Basel Mission made it a priority to alleviate the harsh conditions of child labour imposed by slavery, and the debt bondage of their parents.

As of November 2002, the major countries or regions of operation were Bolivia, Cameroon,[8] Chile, Hong Kong, the Democratic Republic of the Congo, Indonesia, Malaysia, Nigeria, Peru, Singapore, Sudan and Taiwan.
