It's not EUV. China EUV lithography tools are still in the research and development stage. China built a working replica of ASML EUV litho tool. But it has to redesign and work around the original design to avoid patent infringements. One way is to use a different EUV source, instead of using Laser Produce Plasma on Tin (ASML method), they are experimenting with several methods including Laser Produce Plasma on Gadolinium(rare earth) , and Discharge Produce Plasma on Tin.
The following links are summary of China R & D in EUV lithography tools. Note that publication dates are 2013 and 2015. Some of the basic EUV litho R&D go far back as 2008.

They would not know what's inside the machine anyway.

To completely solve semiconductor problem, conservatively estimate, China will need at least 10 years of development and breakthrough.

Without changing the geopolitical situation and even without the semiconductor issue, China still gonna be severely constrained by US.

In 10 years of development time, alot of things will get changed geopolitically.and Taiwan would be one of them.

Can you provide evidence that china has replicated the ASML EUV tools? The links only refer to R&D.

In my pov its a conservative estimate rather than outlandish . We can make a bet if you not buying it.

Huawei already said it plans to have its own domestic production line at 28nm in 3 years.

Each advancing node requires different chemicals.
