How do we get China to stop? It's impossible. It's completely to their advantage to have drones get better. They can mass produce them way better than us. The CPUs don't seem to be that advanced up to now, so they can probably make them. If not they can steal/buy them illegally.

Russia is a slightly different case because they can't make many of the parts but they can cobble them together using other CPUs. So they are hurt, but possibly helped.

We just have to work on defensive measures.
