US president-elect Donald Trump on Tuesday reiterated his expansionist agenda, citing China as a security threat and refusing to rule out military action or economic pressure to reclaim the Panama Canal and acquire Greenland from Denmark.

The Panama Canal Authority chief dismissed President-elect Trump’s claims that China is controlling the trade route and criticized his comments about fees. Ricaurte Vásquez Morales told The Wall

Gordon Chang, expert on U.S.-China relations, joined “Forbes Newsroom” to talk about Trump’s recent comments calling on the U.S. to reclaim control of the Panama Canal.

For weeks, Donald Trump has been stating his intention to take control of the Panama Canal, a critical 51-mile long waterway that connects the Atlantic and Pacific oceans.

The canal executive said China doesn’t control route and U.S. ships can’t get better rates than others.

Panama rejected suggestions of Chinese influence over its canal and dismissed threats of possible US military action on January 7, after President-elect Donald Trump refused to rule out force to regain control of the strategic waterway.
