China is exploring limiting the export of rare earth minerals that are crucial for the manufacture of American F-35 fighter jets and other sophisticated weaponry, according to people involved in a government consultation.

“The government wants to know if the US may have trouble making F-35 fighter jets if China imposes an export ban,” said a Chinese government adviser.

Fighter jets such as the F-35, a Lockheed Martin aircraft, rely heavily on rare earths — a group of 17 metallic elements — for critical components such as electrical power systems and magnets. They are also used in the manufacture of precision-guided missiles and drones as well as most high-tech products from wind turbines to electric vehicles and mobile phones.

The Pentagon has become increasingly concerned about the US reliance on China, which controls 80 per cent of global supplies of rare earths. The US government has made efforts to revive the domestic industry as well as work with allies such as Australia to secure alternative supplies.

Ellen Lord, the top defence official for acquisitions until last year, told Congress in October that the US had a “real vulnerability” when it came to rare earths because China floods the market to destroy any competition any time nations are about to start mining or producing. (FT)
