The Semiconductor Manufacturing Internal Corporation (SMIC) is in the same business as TSMC, if not quite at the same level of complexity or noteriety. The US administration has reportedly threatened it with a blacklisting along the same lines as the one handed to Huawei. This is reportedly linked to the company's alleged connections to the Chinese national military.

>Thanks to its location, it has also been able to remain a supplier to Huawei, whereas the US administration's amended trade restrictions had cut this OEM off from typical partners such as TSMC.
I was expecting a link to this claim, because from what I've heard, SMIC wasn't going to supply to Huawei, most of its raw materials needed come from American and Japanese companies anyway.
