When Marco Rubio arrives in Latin America this weekend on his first foreign trip as Donald Trump's secretary of state, he'll find a region reeling from the new administration's shock-and-awe approach to diplomacy.

Jose Raul Mulino said he won't discuss control of the canal during the secretary of state's visit. Rubio, in contrast, said "we're going to address that topic."

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 and influence in the Arctic and in Latin America.
