Bosnia and Herzegovina is one of the poorest republics in the former federation of Yugoslavia. Bosnia and Herzegovina had to pay a high price for war in terms of a shattering economy whose recovery is slowly picking up only now. The services sector provides the highest percentage of the country's Gross Domestic Product (GDP), followed by industry. Agriculture earns the smallest percentage of the GDP. Industries include oil refining, mining, steel, construction materials, vehicle and aircraft assembly, wooden products, domestic appliances, textiles and tobacco. The tourist industry in Bosnia and Herzegovina is keen to expand. The country's natural environment lends itself to the development of eco-tourism. Its trading partners are Croatia, Italy, Slovenia, and Germany. Bosnia and Herzegovina has implemented a privatization programme and the country is keen to attract foreign investment.
