Now, the US Senate has overwhelmingly passed a bill ordering TikTok's Chinese owners to sell the app within months. We'll see it banned in the United States. It was passed by the House of Representatives over the weekend. All it has to do now is be signed off by the President, President Biden, who's expected to do that as soon as today. But this could be just the start of a long and fierce legal battle. Let's go to our Asia business hub, Surinjana Thawari. Is there following the story for us, Surinjana?

Yes, Sally. The law would require TikTok's owners, a company called ByteDance, to sell the US business within around nine months or face a nationwide ban. Now, TikTok has said it would challenge the law in the US courts, and so is expected to file to sue to stop it through an injunction. Now, there is some precedent for this. Tiktok faced a similar ban in Montana, which was struck down when TikTok sued. And former President Trump also tried to ban both TikTok and Chinese-owned WeChat, but that was blocked by the courts. Now, this process could take many years. So as you see, there is a long legal battle ahead. This has been driven by concerns that China's government could access the data of Americans or survey them with the app. Officials are also concerned that the app's powerful algorithm could influence Americans. Tiktok has said in the past it has not and would not share US user data with the Chinese government, and in recent days has said this law would violate free speech. But the stakes are high, both for the company's footprint in the US, where it has about 170 million users, but also for the advertising and business potential that the US market provides.
