These concerns have gotten larger because of the actions of China. China has said it will put regulations on exports and work to stop smuggling. On September 1, 2009, China said it is going to lower its exports to 35,000 tons per year in 2010–2015. China said that this was done to conserve rare resources and protect the environment. On October 19, 2010 "China Daily" reported that China will "further reduce quotas for rare earth exports by 30 percent at most next year to protect the precious metals from over-exploitation". At the end of 2010 China said that the first round of exports in 2011 for rare earths would be 14,446 tons. This was a 35% decrease from the first round of exports in 2010. In September 2011 China said it was stopping production at three of its eight rare earth mines. These mines produced almost 40% of China's total rare earth production. In August 2012, China said there would be another 20% reduction in production.
