Exactly. This is where vision and commitment comes in. It's just a starting point. China was hugely dependent on foreign semiconductor imports, and their domestic semiconductor companies were laughable. Chinese companies were entirely unmotivated to help with sovereignty and just sourced from the global market because it's so easy. All the Chinese government succeeded in doing was keeping a minimum talent pool alive.
But the US sanction flipped something in the collective consciousness, and Chinese companies finally took the threat seriously. For the past 6 years they have worked tirelessly to de-Americanize the supply chain. Every step was criticized by western "experts" as "oh this doesn't mean much"/"still need ASML/Lam Research/whatever". And they're right, when viewed each step in isolation. Some projects failed, so it was 3 steps forward 1 step back. But now, 6 years later, they're on the cusp of being sanction-proof and even taking a good chunk of global market share.
The reason why the latest two rounds of US semiconductor sanctions didn't completely kill off the Chinese semiconductor industry, and Chinese semiconductor equipment companies kept growing 100%-200% per year, was exactly because 1) the Chinese government kept the minimum talent pool alive even during peaceful times, and 2) they started ramping up de-Americanization a few years before the worst attacks hit.
I hope the EU leaders recognize this partnership is a start and don't just pat themselves on the back with "we've done it, let's bask in electoral glory". Chinese leadership have regular study sessions to study foreign states' policies and their effectiveness. EU leaders should be humble, smart and motivated enough to do the same rather than winging things based on vibes.
