U.S. Secretary of State Marco Rubio has concluded a three-day diplomatic tour of Colombia, Ecuador, and Peru, aimed at strengthening security and economic ties with newly installed conservative governments.

In Ecuador, the U.S. has pledged $45 million and a 110-foot Coast Guard vessel to assist President Daniel Noboa in combating organized crime and illegal mining. Regarding regional security, Rubio clarified that the United States will not conduct unilateral military actions against drug trafficking organizations without the explicit request of allied governments, emphasizing a strategy of coordinated regional operations.

Following these discussions, Rubio conducted a tour of Colombia and Peru. Both nations have formally joined the Escudo das Américas, a U.S.-led coalition targeting transnational organized crime and drug trafficking. This bloc facilitates intelligence sharing and operational support between local agencies and U.S. entities such as the DEA and FBI.

On the economic front, Rubio secured significant agreements regarding critical minerals and rare earth elements to build resilient supply chains for defense and energy transition technologies. In Colombia, the U.S. and the administration of President Abelardo de la Espriella signed memorandums of understanding to cooperate on mining, processing, and civil nuclear energy. These initiatives aim to consolidate a Pacific coast alliance to counter Chinese influence and promote Washington’s security and trade priorities.
