International Campaign to Abolish Nuclear Weapons

Colombia is a signatory of the nuclear Non-Proliferation Treaty (NPT) and has signed but not yet ratified the Comprehensive Test Ban Treaty (CTBT). It is one of the 44 listed countries needed to sign and ratify for the CTBT to enter into force.

Colombia operates one small research reactor with mostly US assistance.

Colombia is also a member of the Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (the Tlatelolco Treaty).
