TikTok began restoring services in the U.S. on Sunday, following President-elect Donald Trump’s announcement that he will reinstate access to the app through an executive order on Monday, according to a report at Reuters.

“Frankly, we have no choice. We have to save it,” Trump said during a rally on Sunday, emphasizing his intention to ensure at least 50% American ownership of the popular video-sharing app, which boasts 170 million U.S. users.

In a statement to its users, the platform credited Trump’s efforts for the app’s return: “As a result of President Trump’s efforts, TikTok is back in the U.S.” The company added that services are being restored in cooperation with its service providers, who now have assurances they will not face penalties.

While some users reported accessing the website of the social media app and basic app functions on Sunday, the app remains unavailable for download on U.S. app stores. TikTok highlighted the app’s significance for over 7 million small businesses in the U.S. and thanked Trump for providing the “clarity and assurance” needed to resume operations.

The announcement comes amid strained U.S.-China relations. Trump has indicated plans to impose tariffs on China but has also suggested a desire for direct communication with China’s leadership. Meanwhile, the Chinese Embassy in Washington criticized the U.S. for “unfair state power” targeting TikTok, vowing to safeguard its rights and interests.

The revival of TikTok highlights its widespread popularity and the high stakes of U.S.-China technology tensions as Trump returns to office.
