MEXICO CITY (Reuters) - The Mexican peso depreciated in international trade after U.S President Donald Trump announced he would impose tariffs on Colombia, reviving concerns about his trade policy.

The currency, one of the most liquid currencies globally, was trading at 20.4630 units per dollar, down 1% compared to the London Stock Exchange Group reference price on Friday.

Tariffs on the South American country are part of a series of actions announced by the U.S. president in retaliation for Bogota's decision to reject two military planes carrying deported migrants.
