There is insufficient evidence to prove that fake text messages were sent by China to spread panic among Americans.
Whereas, an article published by the New York Times said the U.S. intelligence officials assessed that Chinese operatives helped push the messages across platforms to create panic among the American public. It said the origin of the messages remained murky and the American officials declined to reveal details of the intelligence linking with China. Also, the article was based on interviews with six American officials who spoke on condition of anonymity.
However, both the sources did not provide any concrete proof to pinpoint that the Chinese were responsible for spreading the fake messages.
