Why a Taiwanese chip maker is at the heart of US-China tech fight

TMSC, last Thursday, announced a plan to build a $12 billion plant in Arizona, which has been seen as a political win for the US president Donald Trump who promised to bring back manufacturing back home.

Secondly, a day after the TSMC announcement the US Department of Commerce unveiled a rule change that from September would bar global chip makers that use US equipment or technology, (effectively most global industry players including TSMC), from selling to Huawei, which accounts for around 14% of Huawei’s revenue, according to Credit Suisse analysts.
