PUNE, March 30: Sixteen-year-old Peng from Cambodia is a girl with a mission. She has been touring Asian countries since January this year as part of a global awareness drive against child labour. Heading a 40-member team, she arrived here yesterday with an urgent appeal to governments the world over "to stop the exploitation of children" by enacting stringent laws prohibiting child labour. The Asian leg of the global march commenced from the Philippines on January 11 this year and Peng’s team toured the Asian countries as part of their anti-child labour initiative.
