Is it just uneconomic to extract it in other countries? It seems to be a byproduct of aluminum and zinc mining, and those mines are very widespread.

Canada's is a addon to the aluminum production line, ao it might not take a whole ton to expand that production

Isn't GaN already the base for blue led and for all current white-ish led lighting?

Here they are somehow eliminating the need for phosphors for color conversion but they didn't say how.

I mean, if GaN is a problem we are already in a bad shape.

This is why I laugh every time somebody seriously suggests there's going to be a war with China because the West would collapse without Chinese exports. It's just not going to happen.

The problem with outsourcing all your manufacturing so you can mildly increase profits and destroy any organized labor is that whoever you outsourced it to holds you hostage.

Any talk of this is just propaganda to sell weapons and increase the "defense" budget.

So gallium is a byproduct of bauxite mining but requires some sophistication. China produces 60% of the world's aluminum. India is the second largest producer but doesn't have the infrastructure to extract gallium. That will probably change. But it is a sophisticated process so you need an entire supply chain for that too. China has that. India does not (currently).

But India would avoid the geopolitical issues of being dependent on China or Russia.
