Citadel Capital, an Egyptian investment firm, received financing from Citibank to purchase controlling shares in ten companies, and Citibank received the money to finance the Citadel purchases, from the Overseas Private Investment Corporation (OPIC).
The OPIC is a US government agency supporting US investment in the developing world.
The controlling ownership shares of Citadel are held by multinationals. That means, Citadel controls these 10 companies and multinational corporations control Citadel.
It also means that these companies are important enough to both the multinationals, and to the US government, to secure control over them.
