FWIW the huge contingent of Chinese staff that have arrived on site over the last 3 years have spent quite a lot of time in courses and training, learning what is, and what is not acceptable in Europe.
Despite this, i understand about 10% have been disciplined for casual racism, and a small number have been sent home and sacked for more severe acts.
The rate for the local staff (of all colours) is too small to even register, last person to get in trouble of any sort was 4 or 5 years ago.
And thats against a background of a mildly racist culture. Probably worse than the UK.
