Colombia was signatory to the Declaration by United Nations in 1943 , and one of the original 51 signatory countries to the creation of the United Nations ( UN ) at the San Francisco Conference . As such , when the Korean War erupted , and the UN Security Council issued S/RES/83 : Complaint of aggression upon the Republic of Korea and decided the formation and dispatch of the UN Forces in Korea , Colombia was the only sovereign country in Latin America that offered support , by sending a frigate ( afterwards , Colombia also provided an infantry battalion ) . This act , and the subsequent effort and sacrifice of the Colombian troops and sailors on the defense of South Korea have made the relationship between South Korea and Colombia much closer ever since . The Colombian forces deployed in Korea became known as the Colombian Battalion
