The United States has issued a new rule tightening visa guidelines for Chinese journalists, saying it was in response to the treatment of US journalists in China, a shift that comes amid tensions between the two nations over the coronavirus global pandemic.

According to Reuters, the regulation, which will take effect on Monday, will limit visas for Chinese reporters to a 90-day period, with the option for extension. Such visas are typically open-ended and do not need to be extended unless the employee moves to a different company or medium.

Tensions between the United States and China have increased in recent months as the novel coronavirus has swept across the globe.
