NEW DELHI (AP) — The hugely popular Chinese app TikTok may be forced out of the U.S., where a measure to outlaw the video-sharing app has won congressional approval and is on its way to President Biden for his signature.

In India, the app was banned nearly four years ago. Here’s what happened:

WHY DID INDIA BAN TIKTOK?

In June 2020, TikTok users in India bid goodbye to the app, which is operated by Chinese internet firm ByteDance. New Delhi had suddenly banned the popular app, alongside dozens other Chinese apps, following a military clash along the India-China border. Twenty Indian and four Chinese soldiers were killed, and ties between the two Asian giants plunged to a new low.

The government cited privacy concerns and said that Chinese apps pose a threat to India’s sovereignty and security.

The move mostly drew widespread support in India, where protesters had been calling for a boycott of Chinese goods since the deadly confrontation in the remote Karakoram mountain border region.
