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.

The U.S. and Panama are apprehensive about China's presence around the Panama Canal, citing national security concerns. The issue will be a focus during U.S. top diplomat Marco Rubio's visit, where he will meet Panamanian President Jose Raul Mulino and discuss regional migration issues.

Panamanian President Jose Raul Mulino ruled out discussing control of the Panama Canal with U.S. Secretary of State Marco Rubio when he visits the Central American country. "I cannot negotiate and much less open a process of negotiation on the Canal," Mulino said during his weekly press conference, saying the matter is "sealed."
