Colombia-Nicaragua relations

Colombia–Nicaragua relations entail the diplomatic relations between the Republic of Colombia and the Republic of Nicaragua. The relationship between the two Hispanic American countries has evolved amid conflicts over the San Andrés y Providencia Islands located in the Caribbean sea close to the Nicaraguan shoreline and the maritime boundaries covering 150,000 km² that included the islands of San Andrés, Providencia and Santa Catalina and the banks of Roncador, Serrana, Serranilla and Quitasueño as well as the 82nd meridian west which Colombia claims as a border but which the International Court has sided with Nicaragua in disavowing. The archipelago has been under Colombian control since 1931 when a treaty was signed during US occupation of Nicaragua, giving Colombia control over the islands.

In 1985 during the Sandinista revolution in Nicaragua, Colombia headed by President Belisario Betancur was part of the Contadora Group along Panama, Mexico and Venezuela. The United Nations supported group intended to promote peace in El Salvador, Nicaragua and Guatemala, which were engulfed in internal armed conflicts.
