The economy of Afghanistan has steadily improved in the last decade due to the return of large number of wealthy expats, the modernization of the nation's agriculture sector, and the establishment of more trade routes with neighboring and regional countries. The billions of dollars in international assistance that came from expats and outside investors saw this increase when there was more political reliability after NATO became involved in Afghanistan's reconstruction. The nation's GDP stands these days at about $70 billion with an exchange rate of $20 billion (2017), and the GDP per capita is about $2,000. It imports over $6 billion worth of goods but exports about $1 billion worth of legal products, mainly fruits and nuts.
