Recent Senate hearing includes testimony from Helen Toner and William Saunders.
Full hearing here (I haven't watched it yet.)
Thanks for the info.
This is an area where I expect a lot of my info sources to be pretty adversarial, and furthermore I haven't looked into these issues a great deal, so I don't have a developed perspective on how bad-faith the Chinese government's agreements and information sources are.
I think I recall pretty adversarial information-sharing behavior from China toward the rest of the world in March 2020 (which I consider a massive deal), though I'd have to re-read Wikipedia and LessWrong to recall what exactly was going on.
