VIA bought Centaur, so you can argue that, tenuously. VIA is a Taiwanese company. Some people insist that being Taiwanese is being Chinese.
China doesn't seem to be above claiming that they "domestically developed" technology that they really acquired from foreigners. An example I'm aware if is China's "home grown" 3G cellular protocol called TD-SCDMA. It was really a failed European standards proposal from Siemens, but passed off as an indigenous Chinese development for prestige reasons.
The Chinese government has been engaging in some saber rattling because of that.
There's also Native Taiwanese - https://en.wikipedia.org/wiki/Austronesian_peoples, they even make up about 2% of the population, I think they all want the Hans to pickup and leave their lands.
