They did target universities back in the day, which doesn’t mean that the Chinese didn’t have their fingers in the pie, too, along with Cuba, the PLO and ANC. They were all on the same page. China and Russia are enemies for reasons of geopolitics, going back more than a century and a half. Right now, Russia is not communist anymore, but that doesn’t mean they’re warm and cuddly, or that they don’t still cultivate the connections they had from the Cold War, or that China and Russia are not still bitter rivals.
Yeah i am talkint about today. China and Russia have different approaches but Russians are more vicious about distorting narrative.
Chinese are at least economically astute and not overly anti-American and vengeful about the fall of the USSR.
