Donald Trump’s imperialist designs on Greenland, Canada and Panama often sound like the ramblings of a chaos agent who views geopolitics and global trade like a real estate shark chasing new leads.

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.

President-elect Donald Trump said Tuesday he wouldn’t rule out using “military force” to make Greenland and the Panama Canal US territories. “No, I can’t assure you on either of those two,” the incoming president told a reporter asking about the use of military force or economic coercion to acquire the territories.

“The people are going to probably vote for independence or to come into the United States,” said Trump Sr., who wants to buy Greenland from Denmark. The Danish government has repeatedly insisted the ice-covered island is not for sale. “If they did do that, then I would tariff Denmark at a very high level.”

Trump has criticized Panama over increasing fees, warning that if it doesn't change, he will demand the canal's return to the U.S.

Climate change is causing drought conditions that are making the Panama Canal harder to operate and more expensive to pass through.
