The White House said Sunday night that Colombia has agreed to allow the United States to transport repatriated migrants to the country after two U.S. military planes carrying deportees were blocked by Colombia, sparking a flurry of tariff threats between President Donald Trump and the Colombian president.

After Colombian President Gustavo Petro refused to land military aircraft, saying the US "cannot treat Colombian migrants like criminals," Trump ordered "emergency tariffs of 25%" on all imports from the country that would increase to 50% within a week, a "travel ban" on Colombian citizens, and a revocation of visas for Colombian officials in the US, TCH writes.

"These measures are just the beginning. We will not allow the Colombian Government to violate its legal obligations regarding the acceptance and return of criminals they sent to the United States!" Trump wrote on Truth Social.

Hours later, Petro threatened a retaliatory tariff hike of 25% on the US in a series of social media posts attacking Trump and Secretary of State Marco Rubio.

Petro said he opposed the use of military aircraft and the treatment of migrants, but left the door open for Colombia to accept repatriated migrants traveling on civilian planes.

Late Sunday evening, White House press secretary Caroline Leavitt announced that the US and Colombia had agreed to the “unrestricted admission” of migrants from Colombia and would allow them to return to the country “including on US military aircraft, without restriction or delay.”

Leavitt said the US will not sign the tariffs or economic sanctions ordered by Trump "unless Colombia fails to comply with this agreement."

Leavitt said tariffs and financial sanctions would be suspended, but visa sanctions against Colombian officials and stricter customs inspections of Colombian nationals and cargo ships ordered by Trump earlier Sunday would remain in effect "until the first planeload of Colombian deportees is successfully returned."

Colombian Foreign Minister Luis Gilberto Murillo confirmed just moments after the White House statement that deportation flights from the US have resumed.

The escalating trade threats mark the first time Trump has taken major action against another country over its immigration policy since taking office last week.
