Driver Kun Liu (L) and his co-driver Mingji Fang are watched by security personnel as they reattach a wheel before the start of the Stage 10 of the Silk Way 2017 between Hami and Dunhuang, China on July 18, 2017. Dozens of police officers wearing bulletproof vests and toting assault rifles guard the camp of an international off-road race across China's troubled far-western region of Xinjiang. The show of strength at the mobile camp that follows the Silk Way Rally highlights China's concerns about security in Xinjiang, a vast region that has been hit by violence in recent years. The Silk Way Rally, which held its first race in 2009, aims to rival the famed Dakar Rally which has run every January since 1979. / AFP PHOTO / FRANCK FIFE (Photo credit should read FRANCK FIFE/AFP/Getty Images)
