My point, again, in Red China they are sovereign, and the essential control is outside of U.S. hands regardless of the activity taking place. It is much easier for a Fauci type to purposefully turn a blind eye to abuses over there, reducing the odds of getting caught, or invoking plausible deniability of need be.
We cannot effectively monitor and control, so we are best off not doing research over there at all, as you suggested as an option.
