Spoiler: The plan is .. add massive regulation, but only to the US, don't affect other countries developing it in any way other than "setting a good standard that'll hopefully influence them". Seems like an airtight plan.
That's called the carrot
The beauty of the United States' global hegemony is that it also has lots of sticks
If the USA takes up his suggestions, it will have an incentive to work on international frameworks and treaties with competing nations to make the regulation global.
