> It's like, if you complained about the lack of consumer products in Cuba, how could you discuss that without bringing up the sanctions the US has placed on them for decades? Keep in mind Cuba is free to trade with 192+ countries all around the world. Easy to blame everything on the embargo, harder to take a long hard look at the systemic corruption, incompetence, generalized theft and human rights violations plagui…
This is incorrect. Cuba is under secondary sanctions by the US. Any entity that trades with Cuba is liable under US Federal law to get it's assets seized. Granted it doesn't happen as often as it used to, but it's still the law on the books. Since most countries ask for US dollars in order to trade and that these have to be held by US entities, you're basically guaranteed to have assets that can be seized.
Countries don't ask for US dollars in order to trade. Although it is common for some goods to be priced in US dollars, companies (rather than countries) will price and trade in whatever currency suits them, often with assistance from banks providing foreign exchange services. The banks don't need to be US banks, and goods priced in USD do not need to be paid for in USD if you go through an intermediary, which is common practice.
