Abstract: In the background of the "going out" strategy and "the Belt and Road" construction, Chinese enterprises have achieved rapid development in the field of international mining investment in recent years.Democratic Republic of the Congo (DRC), endowed with copper, cobalt, diamond, tin, tantalum, niobium and other mineral resources, occupies an important position in the world.In addition, the government has attracted and encouraged foreign investors in recent years, and DRC has become one of the hottest mining investment markets in the world.The regional geology, infrastructure, development status of mineral resources, and investment environment of DRC are summarized.Cobalt and copper are the most abundant resources in DRC, which are mainly distributed in the Katanga area, southern DRC.The copper and cobalt mining industry, as an important economic pillar, has been actively developed in DRC.The Katanga area is one of the best economic development and infrastructure areas in Congo, and is the best option for mining investment.At present, the problem of power shortage is the main factor restricting the development of DRC mining industry.In the future, with the completion of Busanga and Grand Inga hydropower station, the problem of power shortage will be gradually solved. As the hot land for global mining investment, although DRC has some investment risks in political environment, social security and mining policy, the newly developed diplomatic relations between China and DRC in recent years are the important guarantee for Chinese enterprises to carry out cooperative investments in DRC.Under the background of DRC's joining the Belt and Road Initiative, China and the DRC should continue to strengthen cooperation in energy production and promote sustainable development of mining cooperation.
