In response to the imposition of high tariffs by the US, China has completely ceased exporting rare minerals and ores from its territory, including some rare metals produced only in China. Supplies of rare earth metals and magnets have been suspended, which could impact the automotive, aerospace industries, semiconductor manufacturing companies, and defense contractors. "The cessation of supplies inflicts minimal economic damage to China while maintaining the potential for significant repercussions". The US Customs and Border Protection has added computers, laptops, phones, hard drives, and memory chips to the list of exceptions from import tariffs of 145 percent for China and 10 percent for the rest of the world. Previously, US President Donald Trump stated that there would be no exemptions on tariffs for goods from China.
