“It won't happen!” Trump tweeted.
The president-elect — who spent Monday with advisers at Trump Tower in New York following his holiday respite in Florida — did not specify what, if anything, the United States might do under his command to stop North Korea from developing the missile.
In a second tweet, Trump sought to shame Chinese leaders for trading with the United States but doing little to help stop North Korea's development of nuclear weapons.
He tweeted: “China has been taking out massive amounts of money & wealth from the U.S. in totally one-sided trade, but won't help with North Korea. Nice!”
