[Daily Beast] The Burmese army is fighting a drug lord's troops. Burmese refugees are fleeing into China. The Chinese government isn't sure what to do about it.NANSAN, China -- Nearly every night, just across the frontier in Burma's Shan State, the hills of Kokang are on fire. It stains the fog of Yunnan's mountains, and the border villages see eight hours of twilight. Yet the mood is oddly serene. Locals don't seem too worried about conflict brewing at their doorstep. On the roof of one hotel, the staff has set up a television set so they can keep up with their favorite late-night programs, and they glance only occasionally toward the orange glow, usually as an afterthought to something they hear from that direction. They simply trust that the Burmese will keep the killing to their own side of the border, but recent events suggest otherwise.
