The state-owned firm is the world’s biggest bank, a major force in China’s market, and, according to a ranking by The Banker magazine, the world’s strongest bank based on its amount of capital in 2014. Four big state-owned banks are central to China’s financial system. ICBC is the biggest among them. It has raised money for the Three Gorges Dam project and has been a part of China’s expansion abroad, especially its infrastructure projects in Africa. At the same time, ICBC’s international exposure remains low compared to U.S. and European banks. For a sense of its scale, in 2014 ICBC earned $45 billion, double the profits of Wells Fargo.
