It's unlikely that China will ease its import restrictions on U.S. pork imports, if for no other reason than the country is facing it's own abundant supply of pork. China and Russia have both been hard to budge from their pork import positions put in place following the Type A H1N1 influenza outbreak. Health, government and industry groups have repeatedly emphasized that there's no scientific justification for the continued pork import ban, and like trade issues often reveal themselves, there's more behind the ban than concerns about an influenza virus.  
 
Like the United States, China is now struggling with an oversupply of pork. As a result, China has started buying frozen pork for its government reserves to relieve an oversupply of live pigs that has driven live pig and pork prices below breakeven, reports China's official news service Xinhua.

China's National Development and Reform Commission Price Monitoring Center reports the average live-hog prices in major cities across China fell by 3.75 percent in the last four weeks. Meanwhile, wholesale corn prices advanced 1.2 percent, which of course has pressured farmers' cost of feeding pigs, reports Meatingplace.com

Less than two years ago China suffered vast live-hog losses due to a harsh winter and a bout of blue ear disease (porcine reproductive and respiratory syndrome). The result was a widespread pork shortage in a country where pork is the No. 1 consumed meat. That sent China shopping in the pork export market, benefiting U.S. pork producers in a big way last year. Following that scenario a nervous Chinese government prioritized pork production expansion and provided incentives for large-scale hog production units to restock the long-term supply.
