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.

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.
