How the U.S. Lost Ground to China in the Contest for Clean Energy

WASHINGTON — Tom Perriello saw it coming but could do nothing to stop it. André Kapanga too. Despite urgent emails, phone calls and personal pleas, they watched helplessly as a company backed by the Chinese government took ownership from the Americans of one of the world’s largest cobalt mines.

It was 2016, and a deal had been struck by the Arizona-based mining giant Freeport-McMoRan to sell the site, located in the Democratic Republic of Congo, which now figures prominently in China’s grip on the global cobalt supply. The metal has been among several essential raw materials needed for the production of electric car batteries — and is now critical to retiring the combustion engine and weaning the world off climate-changing fossil fuels.

Mr. Perriello, a top U.S. diplomat in Africa at the time, sounded alarms in the State Department. Mr. Kapanga, then the mine’s Congolese general manager, all but begged the American ambassador in Congo to intercede.

“This is a mistake,” Mr. Kapanga recalled warning him, suggesting the Americans were squandering generations of relationship building in Congo, the source of more than two-thirds of the world’s cobalt.

Presidents starting with Dwight D. Eisenhower had sent hundreds of millions of dollars in aid, including transport planes and other military equipment, to the mineral-rich nation. Richard Nixon intervened, as did the State Department under Hillary Clinton, to sustain the relationship. And Freeport-McMoRan had invested billions of its own — before it sold the mine to a Chinese company.

Not only did the Chinese purchase of the mine, known as Tenke Fungurume, go through uninterrupted during the final months of the Obama administration, but four years later, during the twilight of the Trump presidency, so did the purchase of an even more impressive cobalt reserve that Freeport-McMoRan put on the market. The buyer was the same company, China Molybdenum.

China’s pursuit of Congo’s cobalt wealth is part of a disciplined playbook that has given it an enormous head start over the United States in the race to dominate the electrification of the auto industry, long a key driver of the global economy.

But an investigation by The New York Times revealed a hidden history of the cobalt acquisitions in which the United States essentially surrendered the resources to China, failing to safeguard decades of diplomatic and financial investments in Congo. The sale of the two mines, also flush with copper, highlights the shifting geography and politics of the clean energy revolution, with countries rich in cobalt, lithium and other raw materials needed for batteries suddenly playing the role of oil giants.

The loss of the mines happened under the watch of President Barack Obama, consumed with Afghanistan and the Islamic State, and President Donald J. Trump, a climate-change skeptic committed to fossil fuels and the electoral forces behind them. More broadly, it had roots in the end of the Cold War,…
