How is making it illegal to steal a person’s face and make them say things they never agreed to going to make China an AI super power?

One, fraud is already illegal, and there's plenty of other laws to use in this situation. And none of those laws apply to other countries. A country like China doesn't give a shit, and will gladly use AI to dupe American audiences into whatever they want to manipulate.

Two, as soon as you ask Congress to enact some law to defend against the big bad AI monster under your bed, it's going to go one of two ways:

1. They push some law that's so toothless that it doesn't really do anything except limit the consumer and put even more power into the corporations.
2. They push a law so restrictive that other countries take advantage of the situation and develop better AI than we have. And yes, a technology this important has the ability to give one country a huge advantage.

It's an arms race right now. Either we adapt to these situations with enforcement, education, and containment, or other countries will control our behaviors through manipulation and propaganda. More laws and legislation is not going to magically fix the problem.
