China is stepping up efforts to deal with overcapacity in five sectors, under guidelines released by the State Council, the country's cabinet, on Tuesday.

The industries with serious excess capacity - steel, cement, electrolytic aluminum, sheet glass and shipping - are the key targets, according to the guidelines posted on the government's website.

Steps to reduce excess production in each sector include blocking new projects, shutting down old facilities, reappraising projects under construction and closing illegal capacity.
