It's amazing to see that a country with so much sanctions from USA is still producing almost every product.
Amazing? It should be the norm. Most sanctioned countries start wailing and wining about sanctions and don't develop anything as a reason exists (according to their thought process) why you should keep complaining instead of doing something. Action is what changes an environment.
International trade deals is necessary for an economy to progress and when big boss sanctions a country then most countries will not have any trade deal that hinders their growth compared to the potential they have. But Iran managed to grow despite all the hurdles is what an achievement and they stood as an example that sactions still can't stop them completely but US is losing their dominance so things might turns out differenctly ina decade or two and countries that are not at the top might turn around and reach a better spot in GDP and many other things.
