The UK certainly has its share ("councils expected to fix 2M potholes in FY24"[0] - London, alas, is not getting them fixed all that quickly given how many I've seen in the last 6 months. Greenwich roads, for example, are a disgrace in parts.)
I've never seen as many potholes as when I visited Canada FWIW. I'm a Kiwi and I've driven all over AU/EU/UK (Little bit of US, but only really CA and Maine).
I didn't drive in China, but I've been driven multiple times and the highways and main roads seemed solid.
