Russia's economy worried: dependence on China will be Putin's downfall. In the wake of Western sanctions, several credit institutions are suspending payment transactions with Russia.
China's central banks also want to restrict business with Russia - with disastrous consequences for Russia's economy. Russian oil companies are also faced with payment delays of several months or even transaction refusals because some banks from Turkey, China and even the UAE fear secondary sanctions. The US has been using so-called secondary sanctions for decades to give its primary sanctions more impact. This type of sanctions is intended to prevent individuals abroad from entering into or continuing business contacts with targets by US.
