North Macedonia (along with Montenegro, Bosnia and Herzegovina and Kosovo) belongs to the less-developed southern region of the former Yugoslavia. It suffered severe economic difficulties after independence, when the Yugoslav internal market collapsed and subsidies from Belgrade ended. In addition, it faced many of the same problems faced by other former socialist East European countries during the transition to a market economy. Its main land and rail exports route, through Serbia, remains unreliable with high transit costs, thereby affecting the export of its formerly highly profitable, early vegetables market to Germany.
