The U.S. and Colombia pulled back from the brink of a trade war on Sunday after the White House said the South American nation had agreed to accept military aircraft from San Diego carrying deported migrants.

Colombia has denied entry to two U.S. military deportation flights, according to officials from the Department of Homeland Security and the Defense Department. The flights, carried out on U.S. military C-17 aircraft, were carrying about 80 Colombian migrants each and had departed from California, the defense official told NBC News.

The diplomatic drama that began over the weekend provided clues on how Trump would deal with countries standing in the way of his immigration policies.
