The article doesn't talk about what chips are involved.
It's probably possible to control chips that are specialized and have few users. But other things are probably impractical.
I remember a RUSI report talking about a teardown of one missile and it mentioned voltage regulator chips. Those are everywhere, in all kinds of products. If a new company buys a bunch in China and it turns out that it's a shell company moving them to Russia, there's not a lot you can do, as there's no great way to distinguish them from legitimate users in advance -- there are loads of those. It's like trying to control screws or nails. You can maybe cut off one company if you trace chips back to one, but a bunch of other companies that look indistinguishable from legitimate small companies can be set up in the meantime.
If it's a chip used only in, I don't know, infrared homing systems, then that's probably a lot more practical to place a high bar to access on.
