According to Zhang, he was detained at the border for 48 hours by US officials, who confiscated his phone and laptop, and searched his belongings. He said they questioned him about his ties to the Chinese Communist Party and meetings with friends while in China. At the end of the interrogation, Zhang said he was deported and barred from the US for five years, on suspicion of having shared his research with the Chinese government – an allegation he denies. He is now back in China and mulling his next steps.
“I never imagined this could happen to me,” said Zhang, who – like everyone CNN spoke to for this story – asked to use a pseudonym out of fear of retaliation. “I didn’t know things would get this extreme after Donald Trump returned to office. His administration is jeopardizing my academic future, and I feel powerless to defend my rights.”
