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."

Rubio said he could not predict if Trump would succeed in buying Greenland from Denmark or restoring American authority over the Panama Canal while he is in office.
