Botswana remains one of the best investment destinations in Africa due to its stable political environment and the excellent operational environment it offers, especially in the growth sectors of diamond mining and, to a lesser extent, tourism.

The government is striving to diversify the economy, particularly in manufacturing, beef, agriculture and tourism.
