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.

Secretary of State Marco Rubio said on Thursday he had "zero doubt" that China has a contingency plan to shut down the Panama Canal in the event of a conflict with the U.S. and that Washington intends to address what it sees as a national security threat.

Trump's new top maritime official Louis Sola tells CNBC 'all options on the table' to punish Panama and defend U.S. business, trade and national security.

Panama has owned and administered the Panama Canal for nearly three decades. President Trump wants to change that to counter growing Chinese influence in Latin America.

It’s impossible, I can’t negotiate,” Mulino said when asked about returning the canal to U.S. control. “That is done. The canal belongs to Panama.”

President Donald Trump's suggestion of the U.S. taking control of the Panama Canal has a legal basis partly due to potential treaty violations involving Chinese activities in Panama.

Panama's President Jose Raul Mulino confirms no negotiations with the US regarding the Panama Canal ownership amid discussions on migration and drug trafficking.

Panama President Jose Raul Mulino said Thursday there will be no negotiation with the United States over ownership of the Panama Canal, and he hopes US Secretary of State Marco Rubio's upcoming visit will allow them to focus on shared interests including migration and combating drug trafficking.

Trump could make history by leading the charge for Puerto Rican statehood. He would achieve many of the same goals behind his push for Canada, Greenland and the Panama Canal.

Amid Trump’s bid to acquire Greenland, Rep. Andy Ogles (R-TN) also stressed the need to properly compete with China and “send them back to their own hemisphere.” He added that Trump publicly expressing interest in Greenland is “broadcasting” that “America is great again.”
