President Donald Trump has posted on his social media site that a meeting between the U.S. and Chinese officials went well and that a deal was reached regarding “a ‘certain’ company that young people in our Country very much wanted to save.”

Trump’s comment suggests that the company is TikTok, the social media company associated with China that U.S. law requires to be sold or else cease operations.

The Republican president has repeatedly extended the deadline on TikTok’s fate and was noncommittal on an agreement when asked by reporters on Sunday evening. Trump also said that he would be speaking on Friday with Chinese leader Xi Jinping.

There was no immediate confirmation from China.

TikTok is one of more than 100 apps developed in the past decade by ByteDance, a technology firm founded in 2012 by Chinese entrepreneur Zhang Yiming and headquartered in Beijing’s northwestern Haidian district.

In 2016, ByteDance launched a short-form video platform called Douyin in China and followed up with an international version called TikTok. It then bought Musical.ly, a lip-syncing platform popular with teens in the U.S. and Europe, and combined it with TikTok while keeping the app separate from Douyin.

Soon after, the app boomed in popularity in the U.S. and many other countries, becoming the first Chinese platform to make serious inroads in the West. Unlike other social media platforms that focused on cultivating connections among users, TikTok tailored content to people’s interests.

The often silly videos and music clips content creators posted gave TikTok an image as a sunny corner of the internet where users could find fun and a sense of authenticity. Finding an audience on the platform helped launch the careers of music artists like Lil Nas X.

TikTok gained more traction during the shutdowns of the COVID-19 pandemic, when short dances that went viral became a mainstay of the app. To better compete, Instagram and YouTube eventually came out with their own tools for making short-form videos, respectively known as Reels and Shorts. By that point, TikTok was a bona fide hit.

Challenges came in tandem with TikTok’s success. U.S. officials expressed concerns about the company’s roots and ownership, pointing to laws in China that require Chinese companies to hand over data requested by the government. Another concern became the proprietary algorithm that populates what users see on the app.
