There’s an ambiguity here: what is “this area”? If we’re talking about the semiconductor industry, they’ve been investing billions since the early nineties. The really big push came with the China Integrated Circuit Industry Investment Fund in 2014 at which point they were
plowing billions into the industry across the public and private front. That one fund alone has $100 billion in assets under management at this point, and there are many other funds involved.
They’ve also invested in AI separately (before LLMs) in that time period but I’m less familiar with that sector.
