China has again criticized moves by some countries to ban the use of the video-sharing app TikTok on government devices.
Foreign Ministry spokesperson Wang Wenbin told reporters on Friday that these nations should abide by the rules of the market economy and the principle of fair competition.
The US government was earlier reported to be demanding that TikTok's Chinese parent company, ByteDance, sell its stakes in the app.
Wang said in response that the US has yet to provide evidence that TikTok threatens national security.
He reiterated that China opposes overstretching the concept of national security and abusing state power to suppress foreign companies.
