[...] the very next thing that would happen is that China et al will ask for the same solution.
I think this is actually backwards compared to how it may actually play out. This month's *Harper's Magazine* has an interesting essay about American businesses operating in China. (*Harper's* is paywalled, but you get a few free views per month.) The essay can be found here:
The gist of the essay is that China's authoritarian government strong-arms American businesses, using all of the tools at its command, including outright arrest of business executives, and that this is only going to get worse, to the point where China will be setting U.S. policy by proxy, via business lobbying. After reading that essay yesterday, my guess is that China may someday soon pressure businesses for a backdoor, be granted that backdoor, and that the U.S. government may then get its wish based on China's precedent.
