The U.S. can take a large measure of the credit, or blame, depending on how you want to look at it, for bringing China and Russia together. From Ted Snider at antiwar.com:
Under the pressure of US sanctions, threats, aggression and an imposed Second Cold War, the Russia-China relationship is growing closer and closer.
On December 15, Chinese President Xi Jinping and Russian President Vladimir Putin met for a virtual summit. XI welcomed his “old friend,” and Putin greeted his “dear friend.”
Their greetings to each other were neither scripted nor posturing for the West. In June 2018, Putin told an interviewer that “President XI Jinping is probably the only world leader I have celebrated one of my birthdays with.” He added that XI”is a very reliable partner.” For his part, XI has called Putin “my best, most intimate friend.”
But the growing relationship is not just a friendship between the leaders of the people of the two countries. It is also a growing friendship between the people of the two countries. Relations between Russia and China were not always good. In 2016, before the intense US pressure started pushing the two countries together, only 34% of Russians viewed China favorably; in 2019, 84% saw China as “more a partner than a rival.”
Russia and China have also partnered as the leaders of an important new set of international organizations, like the BRICS nations and the Shanghai Cooperation Organization (SCO). Both of these organizations are intended to balance US hegemony and exceptionalism in international politics. Both of these organizations are huge, each representing nearly half the world, and both are led by Russia and China as the principal partners. Both also include India. The Shanghai Cooperation Organization represents a quarter of the world’s economy and four of its nuclear powers.
