According to Reuters, the US Department of transportation announced on the 21st that it would suspend 44 US flights to China operated by four Chinese airlines. In this regard, Liu Pengyu, spokesman of the Chinese Embassy in the United States, responded that the US move is very unreasonable. We urge the us to stop interfering with and restricting the normal passenger flights of Air China. "Liu Pengyu said that the policy of international passenger flights entering China" applies equally to Chinese and foreign Airlines in a fair, open and transparent manner.
