WASHINGTON, Sept 3 (Reuters) - U.S. Treasury Secretary Steve Mnuchin said on Sunday that he would put together a package of new sanctions to potentially cut off all trade with North Korea after Pyongyang conducted its sixth and most powerful nuclear test.

Speaking on Fox News, Mnuchin said he would ask U.S. President Donald Trump to strongly consider cutting off all trade with new sanctions.

"If countries want to do business with the United States, they obviously will be working with our allies and others to cut off North Korea economically," he said. (Reporting by Joel Schectman; Editing by Lisa Von Ahn)
