Zoom Video Communications will shift to a partner-only model in mainland China from Aug. 23, the company said on Monday.
Users in mainland China may continue to join Zoom meetings as participants, the company added.
The announcement was made as Microsoft confirmed Sunday it is in talks with Chinese company ByteDance to acquire the U.S. arm of its popular video app TikTok and has discussed with President Donald Trump his concerns about security and censorship surrounding such an acquisition.
In a statement, Microsoft said Microsoft and ByteDance have provided notice of their intent to explore a deal resulting in Microsoft owning and operating the TikTok service in the US, Canada, Australia and New Zealand.
The company said it expects those talks to conclude by Sept. 15.
Trump said on Friday that he would soon ban TikTok in the United States. Trump and CEO Satya Nadella have spoken, the company said, and Microsoft was prepared to continue exploring the purchase of TikTok's US operations after their conversation.
