A total of 110 advanced water technologies from 14 countries are on display at today's water exposition in Beijing, a Ministry of Water Resources official said yesterday.

This year's expo, aimed at facilitating domestic and international water technology exchanges, is China's largest in scale to date, director of the ministry's science and technology promotion center Wu Wenxiang said.

"China now invests more energy and money in water conservation than any other country in the world," ministry official Cao Jinghua said.
