South African state owned enterprises play a significant role in the country's economy, with the government owning a share in around 700 SOEs involved in a wide array of important industries. In 2016 the top five challenges to doing business in the country were inefficient government bureaucracy, restrictive labour regulations, a shortage of skilled workers for some high tech industries, political instability, and corruption, whilst the country's banking sector was rated as a strongly positive feature of the economy. The nation is among the G20, and is the only African member of the group.
