Christian Solidarity International

Christian Solidarity International (CSI) is a Switzerland-based Christian NGO with affiliates in the United States, Czech Republic, France, Germany, Hungary, and South Korea. Since 2023, the organization has held special consultative status at the United Nations Economic and Social Council. The organization drew international attention to the resurgence of slavery during the Second Sudanese Civil War as well as for the organization's controversial buy-back-slave campaign which, since 1995, has purchased the freedom of more than 100,000 people.
