The local government of Changji in Xinjiang told miners at the Zhundong Economic Technological Development Park to stop their mining activities, according to a notice "seen and verified" by The Block.Government officials in Zhundong were instructed to end all mining activities under their control by 6:00 UTC (2 a.m. ET) Wednesday.The park covers 15,500 square kilometers and houses coal power plants as well as some of the largest crypto-mining facilities in China, thanks to the wide availability of coal-powered energy.The instruction follows the notice by the China State Council last month calling for a crackdown on bitcoin mining.
