"Liu Kun, a Beijing-based semiconductor industry analyst noted that even if the core component of the 28nm lithography equipment may not be made in China, it would be a breakthrough for the Chinese company to package such equipment.
It may take three to five years for companies like Semiconductor Manufacturing International Corporation (SMIC) to make the 28nm equipment by itself and there is still a long way to go, but Chinese companies are ramping up efforts, according to Liu. "
This is a giveaway quote right here. My bet is 99.9% the above pictured machine has in it foreign parts for the "core component" and SMEE is just packaging it. Hence why they are not being secretive about it because if they purchased a foreign core component for this machine then it cannot be a secret. The reality is China is light years behind, sigh.
