April 19 (Bloomberg) -- China, the world’s biggest cotton consumer, may face a domestic supply shortage on falling output and reduced international supplies for import, an analyst at state-backed CNCotton.com said.

Domestic consumption may outstrip available supply by 3.5 million metric tons in the 2009-2010 marketing year through Aug. 31, and supply will remain tight next year, Mei Yong, a director at the portal owned by China National Cotton Reserves Corp., said at an April 16 conference in Shandong.
