The six countries included in the bill are China, Russia, Iran, North Korea, Venezuela and Cuba, Warner said.
"This competition with China around who dominates technology domains, that really is where the nexus of national security lies going forward," Warner said.
Warner said the bill is not solely meant to address TikTok, and rather should create a "systemic approach" that prevents the need for one-off actions.
"A U.S. ban on TikTok is a ban on the export of American culture and values to the billion-plus people who use our service worldwide.
We hope that Congress will explore solutions to their national security concerns that won't have the effect of censoring the voices of millions of Americans."
