China's presence around the Panama Canal is a national security concern that Panama's government has to deal with, U.S. Special Envoy for Latin America Mauricio Claver-Carone said on Friday, ahead of U.

Secretary of State Marco Rubio says President Donald Trump’s desire to acquire Greenland and retake control of the Panama Canal is driven by legitimate national security interests stemming from growing concerns about Chinese activity in the Arctic and in Latin America.

Some U.S. lawmakers and officials are touting a nearly half-century-old treaty between the United States and Panama to justify the Trump administration's threat to reclaim the Panama Canal - provided it can show the strategic waterway's operation is under threat.
