The Democratic Republic of the Congo is extremely rich in natural resources but has had political instability, a lack of infrastructure, issues with corruption and centuries of both commercial and colonial extraction and exploitation with little holistic development. Besides the capital Kinshasa, the two next largest cities Lubumbashi and Mbuji-Mayi are both mining communities. DR Congo's largest export is raw minerals, with China accepting over 50% of DRC's exports in2012. In 2016, DR Congo's level of human development was ranked 176th out of 187 countries by the Human Development Index. As of 2018, around 600,000 Congolese have fled to neighbouring countries from conflicts in the centre and east of the DRC. Two million children risk starvation, and the fighting has displaced 4.5 million people. The country is a member of the United Nations, Non-Aligned Movement, African Union and COMESA.
