Li Hongrui, head of Khunjerab border inspection station, cleans boundary marker. Li has been working on the border for 27 years.  The highway, built with funds from China during 1966-1978, is the only economic lifeline for Pakistan's northern region. Hundreds of Chinese engineers died while building the road. The Chinese border control authorities and Pakistan's security police hold routine meetings at the area. (Photo: China Daily/Wang Lie)
