Court documents showed that the short video app TikTok asked a US judge to prevent President Donald Trump's administration from imposing a ban on the popular Chinese social media platform.
TikTok and its owner, ByteDance Ltd., have filed a complaint in federal court in Washington against the Trump administration's steps to block the app.
On Friday, the US Department of Commerce announced that the ban on downloading the Chinese-owned WeChat and Tik Tok apps will begin on September 20.
TikTok and ByteDance said in their complaint that the motives for the ban are political, and “it is a violation of the company's rights under the First Amendment of the US Constitution.” TikTok also said that the ban would irreversibly destroy its business in the United States.
The Trump administration, citing national security concerns, said the two widespread apps could be subject to "mandatory cooperation with China's intelligence services".
But opponents of the move say that while the security risks are unclear, the blanket ban on popular online platforms raises concerns about the government's ability to impose regulatory restrictions on freedom of expression guaranteed by the US Constitution.
The decision, which will go into effect on Sunday, bans the download of "Tik Tok", a popular video-sharing application that has about 100 million US users, and WeChat, another Chinese application used for messaging, shopping, payment and other services, with about 19 One million users in the United States.
Officials said WeChat jobs will be affected immediately after the ban goes into effect, although some services may continue to operate.
The Chinese Ministry of Commerce announced that Beijing would take measures against the United States in response to the decision to block the two applications, and in a statement on Saturday expressed its "strong opposition" to Washington's steps against "TikTok" and called on it to stop its actions, describing it as "bullying."
"If the United States does not correct its mistakes, China will take the necessary measures to protect the legitimate interests of its companies," she stressed.
