The Amoy Mission in China, founded in 1842, was the RCA's first organized overseas mission. When all foreign missionaries were forced to leave China, RCA people who had dedicated their lives to China sought places where Chinese people lived. As a result, RCA missionary outreach continued in Singapore, Hong Kong , and Taiwan . More recently RCA missionaries have also begun to work in Indonesia and Laos. The RCA has been involved in mission in India since 1851.
Missionaries work in medical, educational, and community development ministries.
In Nepal the RCA is involved in language survey work. RCA ministries in Asia vary from providing medical care to translating the Scriptures, from teaching English to teaching seminary courses, and from serving as pastors to administering creative outreach and evangelism programs.
