Despite being one of the worst air pollution offenders for decades, China demonstrated improved air quality in 2022, with almost 64% of the 524 cities analyzed in mainland China reporting reduced annual PM2.5 levels. Two cities in its Xinjiang region, Hotan and Kashgar, were ranked the 2nd and 30th most polluted in the world, based on data IQAir gathered between 2017 and 2022.
