BEIJING - China's top legislature on Saturday ended its six-day bimonthly session, adopting a revision to the country's Law on Water and Soil Conservation in a bid to better protect the nation's environment.

The new law has been expected to help reverse China's serious water and soil losses, which are regarded by the Minister of Water Resources as the country's top environmental problem.
