No they don't.
Look at the level of R&D spending in Russia and Iran.
They simply don't have the spending levels and manpower to make much difference in technology development.
And since they are under sanctions, it means technology imports/development is severely constrained.
The only areas which make some sense to cooperate with are aerospace and military tech in Russia.
In every other realm, China is already equal to or better.
Plus Russia and Iran are small economies, so they can't offer a large domestic market for technology products either.
And there is no way that China should make Iran an ally. It will simply drag China into the endless (and unresolvable) conflicts in the Middle East.
And it is not in China's interest to make Russia a formal ally either. Otherwise China will be draPishegged into the land wars in Europe.
Alot of Iranian Compatriots Semiconductors working at US like Bayati, Benhadzi, Khosrwoshahi, Pishevar, Nozad, ,..etc. They can be recruited by iran like China recruiting the thousand talents, bringing the tech Home!
Russians are good at science and physics good for developing equipments,
Good luck for US trying to catch all those Chinese, Russian and Iranian Spies.
This is joint semiconductor development breaking US monopoly , has nothing to do with War, don't be paranoid!
