Zimbabwe doesn't really have much in the way of viable industry, but what it does have, well. Let's just say that Mugabe isn't the one calling the shots in that country: he's becoming more and more of a puppet for the leaders of the army and the leaders of what industry there is, who see him retaining power as the way to keep power for themselves. It could, therefore, be argued that politics is to an extent dictated by industry, and industrial relations, so yes they are intertwined.
