RCA mission coworkers seek to witness through student work, education, translation, and evangelism. In response to requests from the Presbyterian Church in Taiwan, the RCA provides funds to help in seminary education, evangelism among unreached indigenous peoples, disaster relief, and programs of the Presbyterian Church such as the Fisherman's Service Center and the Rainbow Project (a program that serves young girls who have been trapped in prostitution).
In addition to requesting mission coworkers and resources, the PCT seeks the support of its partners in North America and Europe with other issues that face the church. The PCT has encouraged American churches to support Taiwan's acceptance into the United Nations, and strongly supports the independence of Taiwan. It asks its ecumenical partners to stand in solidarity with the church in the endeavor to obtain Chinese recognition of Taiwan's sovereignty.
