Trump issuing ‘emergency 25% tariffs’ against Colombia after country turned back deportation flights

After the president of Columbia blocked a US military plane from landing, Trump threatened retaliatory tariffs on them. He said they would start at 25% and then be raised to 50% in the country. He also noted that there may be a travel ban to the country. I wonder if he would actually do this to a specific country and what the implications would be for the economies of both countries.
