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."

WASHINGTON -- U.S. Secretary of State Marco Rubio will make clear to Panamanian President Jose Raul Mulino in an upcoming visit that the Panama Canal is a strategic asset and cannot be under Chinese control, a senior U.S. official told reporters on Friday.
