The vast majority of carbon wheels and frames are made in Taiwan, but there are well known brands in China and that's what you need to stick with . For wheels, BTLOS is well known and reliable, offering many rim choices, all custom built. Expect $8-900 for wheels with Bitex hubs. I bought wheels with 29mm rim depth, 25mm internal width hookless rims with no spoke access holes and Bitex hubs when there was a free freight offer. No problems so far.
