Team members share a common dream

Guo Jianzeng has worked hard for decades to achieve a world that does not need him anymore.

Guo, a chemical warfare expert in the People's Liberation Army, started training in The Hague on Monday with experts from many other countries in how to inspect and verify the destruction of chemical weapons in Syria. A chemical weapons attack in August reportedly killed 1,429, including 426 children.

"From the scenes shown live on TV, you see a lot of suffering from ordinary people, including children," Guo said.
