Baking != design
Unless you actually design the chips you're potentially screwed.
Even if you design the chips, you still have to make sure that you design any IP blocks you use. It is easy enough to slip attack vectors into something like an ethernet controller.
Then of course you need to make sure you design all the software that compiles the design to gates. It would be relatively easy to sneak in attack vectors in translation software (that's how Stuxnet works).
And of course you have to make sure none of the engineers involved in any of this are above bribery - a hard ask in one of the most corrupt countries in the planet.
At this stage you might as well wrap your whole country in tinfoil and go back to a pre-digital economy.
Nope, this is just political bullshittery - trying to push for greater protectionism for local electronics.
