President Trump is expected to talk with Chinese officials this week about a possible TikTok deal. Here's what we know.

Under a US law, TikTok must be sold or banned in the US by September 17. Trump has seemingly been stuck in a tough spot all year, because the final terms of the deal may not allow current owner ByteDance to own more than 20 percent of the platform or maintain any control over TikTok's algorithm or data-sharing practices.
