Good news. Ive advocates strongly on this forum about building relationships with Germany and wider EU. Glad president Xi is listening to me and not other people here.

Did you write him a new email or just CC'd him the one you wrote Ren Zhengfei? LOLOL
PS. You gave yourself likes with your fake hadoren account but forgot to do it with your gadgetcool account. Drum up your own likes and talk to yourself between them complimenting yourself on how smart you are! Come on, we need a laugh like before!

Commentary on the Chip Wars.
Conclusion
The dispute over Huawei’s access to TSMC has highlighted how vulnerable American industry is to the loss of its sole supply of advanced chips. If the matter cannot be solved by negotiation, China may perceive the restrictions as economic warfare and rapidly escalate, potentially threatening Taiwan. It is not at all clear that Washington has thought through the consequences of its actions here, nor that the current administration has considered chip supply as part of a wider supply chain security and national industrial policy. Given that China has more positive options than the United States, it is surely time for those in charge to consider where this might lead.

The SMEE 28nm Lithography machine should have no problems fabricating Chips in the 7nm node using Multiple Patterning.
What has to be made clear is that all DUV Litho machines (including the latest ASML DUV) will require Multi Patterning to build chips in the 7nm node. Only the latest EUV Machine might be able to build 7nm Chips using Single Patterning. Even current EUV will require double patterning for 5nm.
The TSMC 7nm Chips (7n & 7np) versions were built in 2018/19 completely using the latest ASML DUV Litho and required multi patterning as well. I believe it mainly used double patterning and even a little quadruple patterning.
Even if it is true that the SMEE 28nm Litho has the smallest node at 11nm, it should have no problems making Chips at 7nm using double and quadruple patterning.

Yes I agree with this analysis. I think the initial confusion is whether 28nm represented single exposure resolution or the smallest node practically possible after multiple exposures. Global times article seemed to think it's the second of the two.
to summarize
A) If SMEE new machine is:
28nm single exposure resolution --> This is an pretty amazing achievement and 7nm chips is definitely Possible
B) if it's
28nm after multiple exposure and is the smallest node practical. Then we are light years from 7nm.
Some sources say its A and some say it's B. I want to believe it's A, but there is nothing 100% conclusive.

It's doable, just not slick:
SMIC 7nm process facing lack of high-end lithography machine

SMIC 7nm process facing lack of high-end lithography machine-cnTechPost
SMIC's southern plant, while mass producing 14nm chips, is also building a second production line, of which the 7nm process has been under development for some time, according to IT Times.
But due to the lack of high-end lithography machine, development of the 7nm process isn't moving fast, the report said.
The report quoted SMIC production line staff as saying that due to equipment limitations, SMIC 7~8nm development progress is not fast, the finished product is not so good.
"The same process that TSMC does in one step, we may need three or four steps," The lack of a high-end lithography machine is one of the most critical problems, and "anything but a lithography machine can solve it."
Back in March, SMIC announced that it had purchased the lithography equipment from ASML in the Netherlands, but not the latest EUV lithography machine.
As China's most advanced foundry, SMIC has mass-produced its 14nm process late last year, and the 14nm process contributed 1.3% of revenue in the first quarter and is expected to contribute 10% of revenue by next year.
A major advancement in the SMIC 14nm process is the Unicorn 710A processor, a four A73+four A53 octa-core design with a main frequency of 2.0GHz, which is already used in the Honor 4T series of phones for Huawei.
In addition to 14nm, SMIC also has a modified version of the 12nm process based on the 14nm process, which it said was further reduced in size than the 14nm transistor, with a 20% reduction in power consumption, a 10% performance improvement and a 20% reduction in error rate.
At present, 12nm has started trial production, in-depth cooperation with customers, good progress, in the customer verification and identification stage.
It also has N+1 and N+2 generation processes, in which N+1 process has 20% better performance, 57% lower power consumption, 63% smaller logic area and 55% smaller SoC area compared to 14nm, and the subsequent N+2 process has higher performance and cost.
The N+1 process was completed in Q4 last year and is currently in the customer's product validation stage, with mass production expected in Q4.
