There are many layers of Chinese govt. But GLM is backed by Beijing municipal govt and Tsinghua University.
As far as US EVs being subsidized early, if you take state and federal tax incentives, DoE grants and loan guarantees as subsidizes then that's true.
It's debatable (I think incentives applied to all suppliers not just US ones) but a reasonable statement.
so Tesla technically is subsidized by US govt. SpaceX too. Without NASA funding, they'd be long out of business.
China and US ain't that different.
China realizes that being a tech and industrial powerhouse working on future tech is great for their economy. They bet huge on it. That's how they win.
Europe on the other hand is now a laggard.
In other words, they're not subsidies for Chinese cars being exported abroad. They're not even directly paid to the manufacturers.
