CHINA will face a 500,000-ton deficit in corn production this year, according to the latest report from China National Grain and Oils Information Center. 　
　
The outlook looks set to bring a two-year production surplus to an end after the country ended years of deficit in 2004. The center forecasts that annual corn consumption for 2006-2007 would reach 144.5 million tons, but corn output would be 144 million tons.
