Environment is priority on island

Cleanup, fewer visitors seen as 'win-win strategy'

Weizhou Island in the Guangxi Zhuang autonomous region is also known as China's barrier reef. It's the largest and youngest volcano island in the country and has attracted millions of tourists annually in recent years.

As tourism has developed, local residents who once made a living by raising poultry or fishing now have jobs serving visitors. An estimated 16,000 residents on the island work in the tourism industry.
