More general: as soon as a country (or group of 'friendly nations') reaches a certain technology base, it can start doing things that technology base enables. Will it do so? Of course that also depends on politics & economic factors. This happened for steel smelting, electricity, all sorts of manufacturing, IT, internet access, medicine & so on. Right now, a process node like 7nm is only manufactured in a few places. A decade or 2 from now, that'll likely be a few more (I put my money on India, EU & Brazil. Unsure about Russia given the self-destruct path it has chosen). Some more time, and 7nm is old news that every reasonable tech-able country can do for themselves (should they choose to). Assuming tech keeps advancing, one or 2 high tech hubs will become many.
