There was talk, back in 1990s (iirc?) of europe from Lisbon to Vladivostok. I think it’s a pity we missed that opportunity. I’ve crossed the Russian-Chinese border on a few occasions, years ago, back then it felt culturally that was a european border. Now, the way it’s going, seems more likely Siberia will end up attached to China.
(by the way, wrt OP, China has many many banks…)
