With those who are open for business.
This is basically America telling the world to accept American companies, no questions asked, no matter how big or manipulative. Criticizing other countries for their protectionist self-serving practices. And then literally the second a foreign product gets big and interesting enough forcing their sale to a US domestic entity. This is what America is complaining China does.
The worst part? Instead of trying to find some basis in law as one does in a rule-of-law jurisdiction, they just pulled out the national security™ ban-hammer, which cannot be challenged in a meaningful way. That's straight out of China's playbook. If rule of law is the china shop, national security justifications are the bull.
They just ceded the entirety of what was left of the high ground.

And by the way, the US govt certainly pushes for free trade, but that actually means implementation on a bilateral country-by-country basis (a couple dozen countries or so by now). The public is certainly never going to go for unilateral free trade with anyone who wants to sell anything. I'm sure that's true for almost every country.
What I'm saying is it's largely hypocritical -- telling China they need to open up their markets to foreign businesses from America just the way Americans do for foreign entities, and then once a Chinese company becomes successful enough to garner the slightest bit of attention forcing a sale to an American company. It's exactly the thing America has been accusing China of doing for mandatory joint ventures.
They can do it, by all means, however it further erodes the brand value of America on the world stage as "open for business."
