The Chinese miner has received the necessary internal approvals for its subsidiary CITIC Metal Africa to complete its second investment in Ivanhoe Mines.
It will invest again in miners Rio Tinto and Nutrien, as well as in retailer Walmart after their exclusions from the fund's investments on ethical grounds were revoked.
GDP growth in the DRC is expected to fall to 4.3% this year from 5.8% in 2018, due to a slowdown in mining activity triggered mainly by lower cobalt prices.
