> If the US has an embargo against Cuba because it is a communist country. Why doesn't it trade with China, and up until recently Russia? The US's foreign policy (like most foreign policies) is defined by expediency, and doing business with China is definitely more expedient both in the abstract and in a historical context than business with Cuba. (Besides, the US didn't do very much business with Russia when it was communist. Business picked up after Russia ceased to be communist, under a doctrine of rapid economic liberalization that the US encouraged and helped enact.)
