TOKYO — President Donald Trump says the United States is considering halting trade with "any country doing business with North Korea."
Trump said on Twitter Sunday that the approach was under consideration, "in addition to other options," after North Korea detonated a thermonuclear device in its sixth and most powerful nuclear test.
Treasury Secretary Steven Mnuchin said Sunday that he was putting together new sanctions seeking to cut off trade with North Korea. On "Fox News Sunday," Mnuchin described Pyongyang's behavior as "completely unacceptable."
Trump is meeting with his national security team Sunday afternoon to discuss North Korea.
The president was asked if he would attack North Korea as he left a church service Sunday. He said: "We'll see."
