New York City becomes the latest government to issue new rules banning TikTok, a measure meant to ward off potential security threats from China.

The Verge reported the new ban, which is effective immediately and instructs agencies to delete the app from city-owned hardware within 30 days. NYC Cyber Command, which focuses on cyber threats for the NYC Office of Technology and Innovation, recommended the ban following a security review.

The state of New York also issued its own ban against TikTok on government devices in 2020. Many other states have issued their own bans in recent years, including New Jersey, Ohio, Texas and Georgia.

The U.S. House of Representatives banned the use of TikTok on government devices in December. Earlier this year, the Biden administration escalated its own pressure campaign against the app in an effort to force TikTok to part ways with its Chinese ownership.

In March, TikTok CEO Shou Zi Chew testified before Congress, enduring five hours of questioning from lawmakers over concerns that China might leverage the app to compromise national security. TikTok is owned by Chinese tech giant ByteDance, setting it apart from other major social media companies based in the U.S.

“Let me state this unequivocally: ByteDance is not an agent of China or any other country,” Chew said in his opening statements.
