I don't think ARM could realistically prevent India from manufacturing the CPU, so the architecture probably isn't a barrier to independence. However the 5nm finfet node probably is. The article didn't make it clear but I'm not sure any fab in India can manufacture that kind of thing.

That matches the impressions of TSMC and Apple. The reason I recall is the unreliability of the infrastructure.
