Part of Serbia's strategy to force Kosovo to accept a compromise has been economic pressure - mainly through the refusal to accept documentation that claims Kosovo to be an independent country. Until now it hasn't brought much result.
What made me wonder whether this really works was the lack of demands from Kosovo's society for a solution. It made me wonder whether Kosovo's export sector is simply too small to have political influence.
That would lead to the conclusion that Serbia's best strategy might be to actively encourage Kosovo's export sector. Of course it would need to keep some negotiation chips. But simply hindering Kosovo's exports may be a bad strategy.
