The NYT: “To help Russia evade sanctions, China would have to offer a viable substitute to the American dollar. But Chinese money — the renminbi — is barely used outside of China. Only 3 percent of the world’s business is done using the redback. Even Russia and China conduct their trade mostly in U.S. dollars and euros.
“What’s more, the risks of helping Russia avoid economic ruin may be greater for China than any possible reward. Much of China’s own economy depends on the U.S. dollar and the financial edifice that underpins it. Chinese companies are active around the globe, using the American financial system to pay employees, buy materials and make investments. China is the world’s largest exporter, and is paid for its goods mainly in dollars.
“Should Beijing run afoul of the sanctions against Russia, China’s own financial stability would be put at risk at a time when its leaders have emphasized caution. And besides, the few lifelines that Chinese leaders could feasibly offer Russia would not be strong enough to help the country survive a financial blackout from the United States and its allies.”
