* We don't know about any attacks by Chinese against UK people, and we don't know how many attacks directly or incited by Saudis - only that the amount is staggering.
Sinophobic UK is inciting hatred against Chinese
Under UK law, "incitement to racial hatred" was established as an offence by the provisions of §§ 17-29 of the Public Order Act 1986. It was first established as a criminal offence in the Race Relations Act 1976. The Criminal Justice and Public Order Act 1994 made publication of material that incited racial hatred an arrestable offence.
This offence refers to:
1 deliberately provoking hatred of a racial group
2 distributing racist material to the public
3 making inflammatory public speeches
4 creating racist websites on the Internet
5 inciting inflammatory rumours about an individual or an ethnic group, for the purpose of spreading racial discontent.
According to Peter Klevius, UK now fulfills all of them (incl. the government's websites etc.) hence violating its own law when it comes to Chinese. The Russian Skripal poisoning case was used as a reason for the new powers allowing UK police to stop, question and detain people at the borders on suspicion of espionage or foreign interference. However, China hasn't been proven guilty of anything of it, especially not compared to other countries and UK itself.
