US Secretary of State Marco Rubio has demanded that Panama make "immediate changes" to what he calls the "influence and control" of China over the Panama Canal. America's top diplomat said Panama must act or the US would take necessary measures to protect its rights under a treaty between the two countries.

U.S. Secretary of State Marco Rubio on Sunday warned Panama's President Jose Raul Mulino that Washington will "take measures necessary" if Panama does not immediately take steps to end what President Donald Trump sees as China's influence and control over the Panama Canal.

Panama's José Raúl Mulino announced that his country would not renew its agreement with China's Belt and Road Initiative following a visit from Secretary of State Marco Rubio.
