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 Panama Canal Authority on Wednesday denied the U.S. State Department's claim that U.S. government vessels would be able to cross the canal without paying fees, likely ratcheting up tensions after President Donald Trump threatened to take back control of the crossing.

The Panama Canal Authority said in a statement late on Wednesday that it had not made any changes to charges or rights to cross the canal, after the U.S. State Department said that U.S. government vessels could transit the crossing without being subject to such fees.
