It's Loongarch, some sort of MIPS + RISC-V.
Also from the top of that page I learned that "Loongson" means "Dragon Core" which to me as a westerner makes it sound very clearly Chinese (because dragons) but also a lot cooler (because ... dragons!). Nice.

Also it seems appropriate that the Western concept of a dragon is much less friendly than the Chinese one -- at least, judging from the dances.
They're unrelated things. A Chinese dragon is more like a unicorn than a western dragon.
