Which large integrated swine production and packing company merged with the Chinese company Shuanghui International in 2013?

The correct answer, Smithfield Packing Company, is significant because this merger marked a notable shift in the global dynamics of the pork industry. In 2013, Smithfield, which was one of the largest swine production and processing companies in the United States, announced its merger with Shuanghui International, a Chinese meat processing company. This was a landmark deal as it represented the largest acquisition of an American company by a Chinese firm at that time.

The merger allowed Smithfield to expand its market reach into China, where the demand for pork is exceptionally high, thus enhancing its production capabilities and distribution network. This strategic move not only benefited Smithfield by providing access to a larger consumer base but also strengthened Shuanghui's position in the U.S. market, boosting its competitive edge.

The other companies mentioned do not align with this specific historical event. Tyson Foods, JBS USA, and Cargill are all major players in the meat production and processing industry, but they did not merge with Shuanghui during the same timeframe, which makes the association of Smithfield with this merger uniquely relevant in the context of swine production and international business transactions.
