Economic interdependence was supposed to defuse geopolitical tensions over time – or at least allow the two to be compartmentalized. But today the West is using Russia’s participation in the global economy to punish it for its actions in eastern Ukraine. The EU has announced sanctions that will hit Russia in the banking, oil and defense industries. When China felt its interests were threatened, it was also willing to use economic sanctions in its territorial disputes with the Philippines and Japan. In May, Beijing found itself on the receiving end as Vietnam turned a blind eye to anti-Chinese riots targeting Chinese plants when China put an oil rig in the disputed Paracel Islands.
