Both governments established diplomatic relations in 1936 and a border treaty was signed in 1978.

[3] The border between Colombia and the Dominican Republic is an international maritime boundary that runs through the Caribbean Sea, defined by the Liévano-Jiménez Treaty, signed on January 13, 1978, in Santo Domingo by the foreign ministers of both countries, Indalecio Liévano Aguirre for Colombia and Ramón Emilio Jiménez for the Dominican Republic, and approved by the Congress of the Republic of Colombia on December 12, 1978, through Law No.

This agreement establishes the existence of a Common Scientific Research and Fisheries Exploitation Zone, in which each country has fishing rights and research rights relating to living resources.
