Both Airbus and Boeing enjoy subsidaries - from reseach, Airbus from state owned research, and US from such as NASA, I have no idea, I guess we never find out who get the most.
Airbus have assembly plants both in US ((320 and A220) and China (who also makes A320 copies, Comac, and AR 21 (DC9 copy).
Airbus and Boeing are nowhere as subsided as Chinas effort to build their own civil aircraft industry, wait 20 years and see their cheap planes sell like hot cakes.
Russia have not succeeded with their civil aviation, mainly due to bad maintance, and support.
