Colombia’s President Gustavo Petro has indicated that a suspension of aid from the United States would mean little to his country, but that changes to military funding could have an effect.

“What happens if they take away aid? In my opinion, nothing,” Petro told journalists on Thursday, adding that aid funding often moved through US agencies and employed Americans.

But a cut to military cooperation would matter, he added.

“Now, in military aid, we would have some problems,” Petro said, adding that the loss of US helicopters would have the gravest impact.

US President Donald Trump had threatened over the weekend to raise tariffs on Colombia and said on Wednesday that all funding to the country has been halted.

Colombia was once among the largest recipients of US aid in the Western Hemisphere, but the flow of money was suddenly curtailed this year by the shuttering of USAID, the government’s humanitarian assistance arm. Military cooperation has continued.

The Trump administration has already “decertified” Colombia’s efforts to fight drug trafficking, paving the way for potential further cuts, but some US military personnel remain in Colombia, and the two countries continue to share intelligence.

Petro has objected to the US military’s strikes against vessels in the Caribbean, which have killed dozens of people and inflamed tensions in the region. Many legal experts and human rights activists have also condemned the actions.

Trump has responded by calling Petro an “illegal drug leader” and a “bad guy” – language Petro’s government says is offensive.

Petro has recalled his government’s ambassador from Washington, DC, but he nevertheless met with the US’s charge d’affaires in Bogota late on Sunday.
