Coal trucks to ports will be banned

Only trains will be allowed as part of effort to reduce air pollution

Authorities have put the brakes on diesel trucks transporting coal to and from seaports in northern China. It's one of a series of new measures to cut vehicle exhaust emissions, a senior environmental official said on Tuesday.

Since April, only trains are allowed to carry coal to Tianjin Port. Other ports, including Cangzhou and Tangshan ports in Hebei province, will follow suit in September, under an air pollution action plan for the Beijing-Tianjin-Hebei region.
