Donald Trump fired a warning shot at Central and South American nations on Sunday if they refuse to comply with his plan to send flights of deported migrants back to their country of origin.

The president announced on his Truth Social account he is imposing a 25 percent tariff on all goods coming from Colombia – and the punishment will raise to 50 percent in one week's time. 

It came after Colombia refused to let two U.S. Military flights full of migrants land on their soil on Sunday.

Colombian President Gustavo Petro posted to X Sunday morning insisting he would not allow the U.S. to touchdown with migrants on board military aircraft. 

Petro made good on that promise when he revoked the ability for the military aircraft to land when they approached Colombian air space on Sunday with flights full of their citizens. 

Trump, in retaliation for the order, immediately announced sanctions against the South American country and its government officials.

'I have directed my Administration to immediately take the following urgent and decisive retaliatory measures,' Trump wrote on his social media account on Sunday.

He announced the tariffs, as well as his imposition of 'A Travel Ban and immediate Visa Revocations on the Colombian Government Officials, and all Allies and Supporters.'

All 'party members, family members, and supporters of the Colombian government' also will face visa sanctions, according to Trump's social media announcement.

'These measures are just the beginning,' the president warned. 'We will not allow the Colombian Government to violate its legal obligations with regard to the acceptance and return of the Criminals they forced into the United States!'

Trump ran into early roadblocks with his plans for mass deportation of illegal immigrants this week when Mexico and Colombia both refused to let flights land in their countries.

There were 80 migrants on board each of the two flights bound for South America when the aircrafts' clearances were pulled to land in Colombia.

Now, the Trump administration is working on a deal with El Salvador to accept migrants from third-party nations, which would block them from seeking asylum in the U.S.
