The purchasing power of most Burundians has decreased as wage increases have not kept up with inflation. As a result of deepening poverty, Burundi will remain heavily dependent on aid from bilateral and multilateral donors. Foreign aid represents 42% of Burundis national income, the second highest rate in Sub-Saharan Africa. Burundi joined the East African Community in 2009, which should boost its regional trade ties, and also in 2009 received $700 million in debt relief. Government corruption is hindering the development of a healthy private sector as companies seek to navigate an environment with ever-changing rules.
