Nuclear plant technology sounds to me like something you shouldn't freely be able to sell the IP rights to foreign countries. I suppose steal is probably too dramatic but I'm sure there were some shady dealings associated with this agreement.

With China's attitude recently I dont like the idea of them gobbling up USA's IP and making it their own. So I am biased.

Interesting choice, the company went bankrupt in 2017 building these power plants, the AP1000, in the United States. The only plants they managed to build before the bankruptcy are in China. After the bankruptcy, China stole the design and are building their own versions of it as they own the patent rights. Not a very great track record to go with. They only exist today because of an acquisition by a private equity group.
