Teddy Roosevelt once declared the Panama Canal “one of the feats to which the people of this republic will look back with the highest pride.” More than a century later, Donald Trump is threatening to take back the waterway for the same republic.

President-elect Donald Trump over the weekend suggested the US should retake the Panama Canal, an idea that was immediately rejected by the government of Panama, which has controlled the passage for decades.

The status of the Panama Canal is non-negotiable, President Jose Raul Mulino said in a statement Monday signed alongside former leaders of the country, after Donald Trump's recent threats to reclaim the man-made waterway.
