Anybody knows what best chips resolution CETC could produce? 32nm or 28nm ?

I don't think so, they do make steppers for military chip fabrication, i have heard that they have 65nm-45nm capabilities but probably at low performance that for low volume military chips is probably good enough.

So you're neither Taiwanese nor Chinese?
We can judge for ourselves, thanks. Let me just remind you that experts know experts, and can always find out who is bullshit and who isn't eventually.
Refurbished systems are typically bought for cost, not for performance. For performance you need not only the actual equipment but installation and application engineers to figure out the best way to use your equipment - which is best done for new equipment.
Canon sells brand new KrF front end systems:
Here's SMEE KrF front end system:
As some of you were discussing whether SMIC would go for western equipment for their new fabs, here is a fresh letter from Marco Rubio to Gina Raimondo, requesting for more sanctions against SMIC, in the light of recent record breaking revenue growth from SMIC.

I do remember that in the past pages that SMEE was said to be ramping up production in 2022 and a bit older post saying it in mid 2022. You can’t expect there to be dozens of system ready when they just started producing them for the first time.
YMTC is also in the hit list of this people.
Like I said if Chinese semiconductor fab companies are not working 24/7 with Chinese semiconductor equipment, sub-systems and material providers, I think they are committing suicide.
YMTC is actually the most localized of all as they're not listed and they recently did a supply chain and IP audit to ensure no foreign interference is possible.
28nm. Much of the Chinese military chip production appears to be 40nm and higher. Always remember that the smaller the nm is, the more susceptible the chip is to EM interference, EMP, cosmic rays in the higher atmosphere, and so on, so there is a limit to how far any military will accept smaller and smaller nm. This is why going to another chip making technology like graphene or going to 3D stacking, might be a more attractive idea.
Remember this picture? Note that "20" on the third item should stand for J-20, while the others are for J-16 and J-10B. It also describes the modules used for the "-20" radar uses 3D MCM. The infographic describes three generations of AESA radars, starting with the J-10B at Gen 1.5. The four digits represent the number of elements so the J-10B is 12XX, the J-16 at 1760, and the J-20 at 1856.
