The US government late on Friday accused the Chinese government of making it impossible for US airlines to resume service to China and ordered four Chinese air carriers to file flight schedules with the US government.
The administration of President Donald Trump stopped short of imposing restrictions on Chinese air carriers but said talks with China had failed to produce an agreement.
The US Transportation Department, which is trying to persuade China to allow the resumption of US passenger airline service there, earlier this week briefly delayed a few Chinese charter flights for not complying with notice requirements.
