This looks more like propaganda to me. TSML were at 3nm in 2020. SMIC are only at 4nm today? ASML have had a lot of pressure from the US not to sell to Chinese companies. So who is supplying the machines for manufacturing them? There's not much detail in that clip, only letting everyone know SMIC are making headway. It costs 9 billion US dollars to build a new fabrication line for new chips. I don't think TSMC or the likes of Apple, Nvidia, AMD or any company they manufacture for will be to concerned for a while yet. I think Samsung is ahead of SMIC at the moment. It did let everyone know there is competition coming up.
