Here's every country that has banned TikTok as the US threatens a nationwide ban. Montana is the first state to pass a total ban.

• Montana on Wednesday became the first state in the US to sign a bill banning the social media app TikTok.
• A growing number of countries are partially or totally banning the app over security concerns.
• The US has threatened TikTok's Chinese parent company with a ban if it doesn't sell to another company.

A growing number of countries, states, and other entities are placing partial or total bans on TikTok amid data security concerns, citing fears that its Chinese parent company, ByteDance, could be forced into giving user data to the Chinese government, or be pressured into amplifying or suppressing certain topics based on China's interests.

The US recently threatened the app with a potential nationwide ban if its Chinese owners don't sell their ownership stake, but TikTok has said forcing a change in ownership would not address national security concerns. And Montana became the first state to approve an outright ban of the app in May.

TikTok has fought the talk of bans. A spokesperson previously told Insider. "The best way to address concerns about national security is with the transparent, U.S.-based protection of U.S. user data and systems, with robust third-party monitoring, vetting, and verification, which we are already implementing."

Here's a running list of countries and other places with a partial or total ban on TikTok:
