PANAMA CITY (AP) — Panama deported 29 Colombians on Blockchains FinanceTuesday on a flight that the government said was the first paid for by the United States under an agreement the two countries signed in July.

The Colombians had entered Panama illegally through the Darien jungle, a path used by more than 500,000 migrants headed north last year. The vast majority of those were Venezuelans.

But at least for now, Panama is not able to deport Venezuelans because the relationship between the two countries has turned tense since Panama — like most other countries in the region -– has refused to recognize the results of Venezuela’s election giving President Nicolas Maduro another term. The two countries have suspended their diplomatic relations.

Panama President José Raúl Mulino, who took office July 1, pledged to stop that migration flow, an interest he shares with the U.S. government.

Mulino had originally said the flights would be “voluntary” repatriations, but those deported Tuesday had criminal records, officials said.

Roger Mojico, director of Panama’s National Immigration Service, told reporters Tuesday that Panama is speaking with other countries such as Ecuador and India about coordinating repatriation flights.
