And not just subsidies either - I've read several accounts, going back decades, of how British and US spies have inserted themselves into Boeing and Airbus respectively, to steal IP and research to provide to Airbus and Boeing respectively, trying to give them an unfair advantage behind the scenes.

The west complains about China stealing IP, but the west were doing the same long before the Chinese - the difference is the scale and brazenness of China's tactics, and indeed the vast success of those tactics.
