this from people within the mainland? >> that's interesting. there are five to 6,000 chinese nationals in ukraine. because the chinese government has been brushing aside the u.s. warning about a war there. and of course they're trapped and because of their comments here in china some of them having translated in ukraine. reporting growing hostility towards chinese nationals still in ukraine. they're actually posting messages begging back home to stop and antagonizing ukraine during the delicate time. now the chinese government promised to get them out as soon as they can. the air space is closed. that's going to be difficult to evacuate them now. that's really one of those real life consequences of this country's policy. and how the social media platforms have been reacting to this war in ukraine. >> certainly interesting. the european countries calling for its citizens to leave ukraine week ago.
