Unlike China who can definitely get real buddy buddy with everyone around them.
Eh, I don’t know. I think they fucked up lots of relations with their neighbors as well due to the same imperialistic politics. They have shitty relations with Japan, SK, Taiwan, all the nation in the South China Sea, Vietnam and India. Relations with Russia, and USSR before that, have always been a bit tense (Mongolia issue, plus claims over Vladivostok). The rest are minor nations, mostly under the sphere of influence of other empires.
From what I can see, they are trying to create a sphere of influence of their own in Asia, propping up the new dictatorship in Myanmar, helping the Pakistani and trying to snatch up the central Asian “-stan” nations from Russia’s influence. Success is mixed.
Anyway, economically speaking these are not real partners like the western block, but more like client states. The real economic partners of China remain the western nations. Without them China’s trade would be non-existent.
