The US will ban the use of WeChat Sunday to “safeguard the national security of the United States.”

The Chinese app TikTok will also be banned by Nov. 12, but Commerce Secretary Wilbur Ross said early Friday on Fox Business News that access to that app may be possible if certain safeguards are in place.

“At the President’s direction, we have taken significant action to combat China’s malicious collection of American citizens’ personal data, while promoting our national values, democratic rules-based norms, and aggressive enforcement of U.S. laws and regulations, ”Ross said in a prepared statement.
