In response to Chinese Hotels Refuse Foreigners (caring)

There are hotels around China and in Beijing that discriminate against all people from
abroad

Foreigners with visas (I'm not sure what the situation is for someone with an actual 'green card'; they are few and far between in China) must stay at hotels that have the capacity to register the foreigner with the local PSB. Routinely, that is now an on-line transaction but it requires that the hotel have the equipment AND the permission to book foreigners into their hotel. All 4 and 5 star hotels have that capability and many, if not most, 3 star hotels.

The Chinese government would say that this is to protect their 'foreign guests', but of course it is to keep track of them.

If South Africa had required that blacks could only reside in 4 & 5 star hotels, I doubt that Mandela would have achieved much traction in his 'regime change'.
