I'm pretty sure the Chinese airlines have been told to continue by the central government to allow PRC citizens to come back home. But with the current spate of border closures, I'm not sure how Air China/ Hainan etc will be able to operate to US/ Australia/ Singapore etc, since I presume the vast majority of their staff are not citizens or LPRs of the respective countries. Is the US, for example, making an exception for Chinese (or Malaysian, whatever) cabin crew?
