Noble Group Ltd would sell its remaining 49 percent stake in its agribusiness to China's state-owned COFCO International Ltd, exiting agricultural markets as Asia's biggest commodity merchant seeks to slash debt. The $750 million cash deal will hand COFCO full ownership of Noble Agri, which will be renamed COFCO Agri. It will handle everything from corn to sugar to cocoa and fertilizer, as China, the world's top commodities buyer, seeks greater access to food.
