The most urgent task is to check water pollution to ensure the safety of drinking water, and we must win that battle.

The issue of pollution has become a blasting fuse for social instability.

If environmental protection efforts continue to lag behind economic growth, pollution will become even more rampant.

The worst environmental pollution in the country is coming, highlighted by frequent occurrence of major pollution incidents.

The result would be terrible if incidents happened in these factories.

I hope monitoring cross-border rivers is just a beginning of the two countries' co-operation on environmental protection. China and Russia need to jointly develop comprehensive environmental protection.
