That is true, but I would say that transnational units of, say, 1 billion people and more, should at least strive to be as resilient to blackmail as possible. The current situation is such that if China and the US decide to sanction any third party at the same time (be it India or the EU or Russia or Saudi or whoever), the targeted party will suffer like hell. Sure, as of 2026, this sort of coordinated action between current Chinese and American leaders seems unlikely. But leaders change. Sometimes in the most unlikely way.
