The Donald Trump administration on Wednesday moved to block Chinese airlines from flying to the US.
Relations between the two countries have also soured in recent months amid escalating tensions surrounding the coronavirus pandemic.
The order, published Wednesday, takes effect June 16, but it could be moved up.
Delta Air Lines and United Airlines have asked to resume flights to China this month, even as Chinese carriers have continued U.S. flights during the pandemic. Delta said in a statement on Wednesday that “we support and appreciate the U.S. government’s actions to enforce our rights and ensure fairness.” United did not immediately comment.
China “remains unable” to say when it will revise its rules “to allow U.S. carriers to reinstate scheduled passenger flights,” the Transportation Department said in a formal notice made public on Wednesday.
The Chinese embassy in Washington did not immediately respond to a request for comment.
In March, Chinese aviation officials said Chinese airlines could keep flying one scheduled passenger flight a week, on one route to any country, a measure aimed at preventing the spread of the coronavirus.
