Negotiations for China’s entry into the World Trade Organization have hit another snag, this time over China’s insistence that it be allowed to subsidize agricultural output on the level of a developing country, rather than a developed country, according to the Dow Jones Newswire.

Under WTO rules, countries classified as developing can subsidize up to 10 percent of farm output, while developed countries can only go as high as 5 percent.

China maintains it should enter the WTO as a developing country in regards to agriculture, despite opposition from the United States, Canada, Brazil and Australia, among other countries. A compromise is likely, but this has set the timeline for China’s WTO entry back once again.

China’s induction into the WTO holds special interest to pork producers. The 1.2 billion people in China eat about 21.5 kilograms of pork each annually. In addition, most of China’s pork production is of the backyard variety, and the cost of production is too high to be competitive with the United States.

The potential for U.S. pork exports to China is huge. Dermot Haye, Iowa State University agricultural economist, says if China were to join the WTO and the U.S.-China agreement were implemented fully and fairly, exports to China could add $12.50 per hog marketed over the course of the next 10 years.
