My guess, 20-25%. Not the majority, but the most of any country. Let me look it up.
Jan 2024 - 10%, 2nd to Japan. Down from 20% in the past, and the lowest % since 2009.
Okay, so I was sorta-kinda in the ballpark. I think my point still holds true - China isn't going to stop sending us their stuff, holding out for a payment because without our purchasing of so much of their stuff, it would screw them and us.
