Zimbabwe's economy is growing despite continuing political uncertainty. Following a decade of contraction from 1998 to 2008, Zimbabwe's economy recorded real growth of more than 9% per year in 2010-11, before slowing to 5% in 2012, due in part to a poor harvest and low diamond revenues. However, the government of Zimbabwe still faces a number of difficult economic problems, including infrastructure and regulatory deficiencies, ongoing indigenization pressure, policy uncertainty, a large external debt burden, and insufficient formal employment.
