Protesters took to the streets on Monday (30 May) in Inner Mongolia after Han Chinese coal truck drivers killed a Mongolian herder who attempted to stop them from trespassing on grasslands. Chinese officials have sought to stifle the protests in the region by tightening security, censoring coverage of the event, and promising to punish the perpetrators. There has been growing tensions between herders and coal miners over the use of the grasslands, which cover reserves of coal, natural gas, and rare minerals. Local sources link the protests to a deeper resentment among Mongolians over their marginalisation by the Chinese.
