Hmm, the "specifically ASIC chips" is a questionable area as China has NO advanced Foundries capable of producing 16nm and under chips. TSMC is Taiwanese-owned company and all of their advanced foundries are located in Taiwan. If you want to do business with TSMC don't even suggest to them as a joke that they (Taiwan) are part of China....

True Bitmain, Canaan, and others contracted TSMC to make their chips but technically the chips are not Made In China.
