As for the world, there are no bosom friends. You know, the Soviet Union and China were such close friends as "Sino-Soviet friendship lasts forever", "comrades plus brothers" and "big brother of socialism", and both sides could wear a pair of trousers. In the end, either turn against each other or turn against each other. They call us the scum of socialism, and we call them Su Xiu red empire Doctrine. So Russia is much smarter now, and everything is based on its own interests, just like the famous saying: there are no eternal enemies and friends, only eternal interests.
