That sounds like an exaggeration? My impression is that China has OK/good relations with countries such as Vietnam, Cambodia, Pakistan, Indonesia, North Korea, factions in Myanmar. And Russia, of course. If you’re serious about this claim, I think you should look at a map, make a list of countries which qualify as “neighbors” based purely on geographic distance, then look up relations for each one.
