The official mouthpiece of the Chinese Communist Party, the People's Daily, warned on May 30 that China might ban export of rare earths — which are crucial in much high-performance modern technology including Circuit boards, batteries, sensors and thrusters. It warned "Will rare earths become a counter weapon for China to hit back against the pressure the United States has put on for no reason at all? The answer is no mystery. Don't say we didn't warn you!" The nationalistic Chinese newspaper Global Times also separately warned that China has plenty of ways to retaliate against the US, including the threat of cutting off supplies of rare earths.
