7nm node is a marketing term and non-Chinese companies have been making this chip generation since 2016.
Samsung and TSMC have been making 5nm generation chips for almost three years now.
So yes, there may be a technological/sanctions aspect to China having homegrown 7nm production but:
They are still years behind the rest of the world, it’s unclear how good these 7nm chips actually are, it’s unclear what their volume is, or their ability to improve further.
