TSMC’s clients include Huawei’s chip division HiSilicon. However, the U.S. blacklisting of Huawei over security concerns and trade disputes with China has left the world’s biggest contract chipmaker exposed to diplomatic developments between two countries where it also has production bases.
The company last month unveiled plans for a $12 billion plant in the United States just hours before the U.S. Commerce Department outlined a proposal to amend chip export rules – a move that would restrict TSMC’s sales to Huawei.
