Microsoft’s Windows and foreign database programs also sidelined as Beijing favours Chinese hardware and software

Among the 18 approved processors were chips from Huawei and state-backed group Phytium. Both are on Washington’s export blacklist. Chinese processor makers are using a mixture of chip architectures including Intel’s x86, Arm and homegrown ones, while operating systems are derived from open-source Linux software.

That does not mean they are immune. There will be likely immune to the same affecting amd or intel CPUs but not to speculative execution bugs in general.

Every CPU that uses speculative execution (so basically every modern CPU) is potentially vulnerable to those kinds of attacks.
