India has been a battleground for the Trump administration's effort to get allies to shun Chinese technology, especially cellular equipment from Huawei, over what the White House says are national-security concerns.

Officials in the U.S. and allied countries have said China's authoritarian government could order Huawei to potentially spy on or disrupt communications, The Wall Street Journal reported last year.

U.S. regulators are weighing whether TikTok poses a national-security risk because it is owned by China-based Bytedance. Bytedance's 2017 acquisition of the startup Musical.ly, a lip-synching app that had won a large following among U.S. teenagers, is under review by the Committee on Foreign Investment in the United States for potential national-security risks. Bytedance shut Musical.ly after merging it with TikTok in 2018 -- a move crucial to its success in the U.S. because of Musical.ly's use there. Several U.S. lawmakers have accused the company of censoring content at Beijing's behest -- which Bytedance has denied.

In March, Sen. Josh Hawley, a Republican from Missouri, proposed a bill to ban federal employees from using TikTok on their government-issued phones as concerns increase about Chinese tech firms sharing user data with Beijing. Several U.S. agencies, including the State Department and the Department of Homeland Security, have already barred employees from using the app.
