SummaryCompaniesGlobal automakers warn of production halts without China's critical mineralsExecutives and diplomats are scrambling to get meetings in BeijingTrump and Xi expected to talk this week amid trade war June 3 (Reuters) - Alarm over China's stranglehold on critical minerals grew on Tuesday as global automakers joined their U.S. counterparts to complain that restrictions by China on exports of rare earth alloys, mixtures and magnets could cause production delays and outages without a quick solution. German automakers became the latest to warn that China's export restrictions threaten to shut down production and rattle their local economies, following a similar complaint from an Indian EV maker last week.

The move underscores China's dominance of the critical mineral industry and is seen as leverage by China in its ongoing trade war with U.S. President Donald Trump. Trump has sought to redefine the trading relationship with the U.S.' top economic rival China by imposing steep tariffs on billions of dollars of imported goods in hopes of narrowing a wide trade deficit and bringing back lost manufacturing.

China has responded with its own tariffs and is leveraging its dominance in key supply chains to persuade Trump to back down. Trump and Chinese President Xi Jinping are expected to talk this week, White House spokeswoman Karoline Leavitt told reporters on Tuesday, and the export ban is expected to be high on the agenda. "I can assure you that the administration is actively monitoring China's compliance with the Geneva trade agreement," she said. "Our administration officials continue to be engaged in correspondence with their Chinese counterparts." Trump has previously signaled that China's slow pace of easing the critical mineral export ban represents a violation of the Geneva agreement.

Once in place, the new system could permanently prevent supplies from reaching certain companies, including American military contractors. The suspension has triggered anxiety in corporate boardrooms and nations' capitals - from Tokyo to Washington - as officials scrambled to identify limited alternative options amid fears that production of new automobiles and other items could grind to a halt by summer's end. "If the situation is not changed quickly, production delays and even production outages can no longer be ruled out," Hildegard Mueller, head of Germany's auto lobby, told Reuters on Tuesday. Frank Fannon, a minerals industry consultant and former U.S. assistant secretary of state for energy resources during Trump’s first term, said the global disruptions are not shocking to those paying attention. “I don’t think anyone should be surprised how this is playing out. We have a production challenge (in the U.S.) and we need to leverage our whole of government approach to secure resources and ramp up domestic capability as soon as possible. The time horizon to do this was yesterday,” Fannon. Diplomats, automakers and other executives from India, Japan and Europe were urgently seeking meetings with Beijing officials to push for faster approval of rare earth magnet exports, sources told Reuters, as shortages threatened to halt global supply chains. A business delegation from Japan will visit Beijing in early June to meet the Ministry of Commerce over the curbs and European diplomats from countries with big auto industries have also sought "emergency" meetings with Chinese officials in recent weeks, Reuters reported. India, where Bajaj Auto (BAJA.NS), opens new tab warned that any further delays in securing the supply of rare earth magnets from China could "seriously impact" electric vehicle production, is organizing a trip for auto executives in the next two to three weeks. In May, the head of the trade group representing General Motors (GM.N), opens new tab, Toyota (7203.T), opens new tab, Volkswagen (VOWG.DE), opens new tab, Hyundai (011760.KS), opens new tab and other major automakers raised similar concerns in a letter to the Trump administration. "Without reliable access to these elements and magnets, automotive suppliers will be unable to produce critical automotive components, including automatic transmissions, throttle bodies, alternators, various motors, sensors, seat belts, speakers, lights, motors, power steering, and cameras," the Alliance for Automotive Innovation wrote in the letter.
