Latin American leaders have canceled a summit to discuss Donald Trump's migrant crackdown, as the region weighs the risks of openly confronting the firebrand US president. But Honduras was forced to cancel the meeting after no prominent regional leaders apart from Petro confirmed their attendance.

President Donald Trump and Colombian President Gustavo Petro defended their views on social media and imposed tariffs on each other’s goods.

Colombian President Gustavo Petro announced that Colombia was suspending permission for previously authorized U.S. deportation flights to land in Colombia. Ostensibly driving Petro’s action were concerns that Colombian nationals were not being treated with respect during the deportation process because they were being transported by military aircraft.

BOGOTA, Colombia (AP) — President Donald Trump said Sunday that he was ordering tariffs, visa restrictions and other retaliatory measures to be taken against Colombia after its government rejected two U.S. military flights carrying migrants.

Trump said the measures were necessary, because the decision of Colombian President Gustavo Petro “jeopardized” national security in the U.S.

The Community of Latin American and Caribbean States (CELAC) has called for an "emergency" meeting of member states after the tariff standoff between the United States and Colombia on Sunday. "Migration" and "Latin American and Caribbean unity" are two of the three topics listed on the agenda, the other one being "Environment."
