China has made massive breakthroughs. In chips, SMIC/Huawei are advancing impressively in terms of products, but it is unclear how good yields/costs are, even if they are shipping commercial products.

Still, this PR does give hints that this is Garage hacked EUV with cannibalized parts they cannot make yet, and 4 year time scale is far out enough. There was PR of EUV breakthrough this spring too, and don’t recall if this claim is additional advancement over that.
