the important question to answer is should I buy Argentinian red wine?
The answer to your question is yes – if you want to help European car manufacturers.
Argentina does things differently and sees trade as a two way traffic, so for example if a European company wants to import something then they have to export something else. Which has led to a situation whereby a company such as Mercedes-Benz needs to export Argentine wine in order to be able to import their vehicles into Argentina. So buy Argentine wine if you want to help German car manufacturers, otherwise the choice is simply down to you.
BTW protectionism is a central feature of Peronism, and Cristina Kirchner is very much a Peronist. For the record I’m not personally a Peronist, far from it – I’m actually very hostile to Peronism, but I am a very strong supporter of Cristina Kirchner. Which I know all sounds very contradictory but it stems from a realistic and pragmatic commitment to the greater good.
