U.S. President Donald Trump has postponed a phone call with Panamanian President Jose Raul Mulino due to last-minute changes in the U.S. leader's agenda, Panama's government said on Friday, amid tensions over U.

Panamanian President José Raúl Mulino on Thursday denied the U.S. State Department’s claim that his country had reached a deal allowing U.S. warships to transit the Panama Canal for free. Mulino said he had told U.

The Panamanian leader says he was “incredibly surprised” by the statement, as President Trump threatens a U.S. takeover of the strategic waterway.

Panama denied a claim made by the State Department on Wednesday that the Central American nation had agreed to no longer charge fees for US government ships to transit the country’s famous canal.

The State Department claimed it had struck a deal that would save the U.S. government “millions of dollars a year.”

President José Raúl Mulino on Thursday denied a claim by the Trump administration that this Central American country had agreed to eliminate tolls for U.S. government ships using the Panama Canal, in an apparent setback to U.

Conservative President José Raúl Mulino wanted to work with Trump from day one. He’s now trying to stop a U.S. takeover of the Panama Canal.

Panama President Jose Raul Mulino said on Thursday the U.S. was spreading "lies and falsehoods" after the State Department claimed U.S. government vessels would be able to pass through the Panama Canal without paying.
