Workers process meat at a plant of Shineway Group, also known as Shuanghui Group, in Luohe city in central Henan province in this May 13, 2006 file photo. China's Shuanghui International Holdings, which bought U.S. pork producer Smithfield Foods Inc this year, has hired banks for a Hong Kong IPO, seeking to raise up to $6 billion in what could be the region's largest stock offering in four years. The potential size of a deal is subject to change. While one source familiar the matter said it could go as high as $6 billion, another said it was more likely to be in the $3-4 billion range.
