Trump Must Shift Focus of Tough Diplomacy from Allies to Adversaries — The Hill.

The Panamanian government has decided to focus on Chinese activities and withdraw its participation from the Chinese initiative 'One Belt, One Road,' which poses a threat to U.S. national security. This could lead to the closure of the Panama Canal, a key route for the movement of American military forces between the Atlantic and Pacific Oceans. President Trump has raised concerns about the financial issues related to transit through the canal.

To gain concessions from Colombia and Mexico, President Trump is employing tough positions and threats of tariffs. Analyst Joseph Bosco notes that this tactic may negatively impact international respect for the U.S. and yield mixed results.
