Entrepreneur pushes Chinese role in global credit BEIJING (AP) - Guan Jianzhong is waging a one-man crusade to change the global credit rating industry. His argument: China and other cash-rich developing nations shouldn't have to rely on ratings agencies in the deeply indebted United States. The chairman of Dagong Global Credit Rating Co., which is little known abroad, issued its first ratings of government debt in 2010 and declared the U.S. a worse risk than China. Its announcement caused barely a ripple. Months later Standard & Poor's cut America's prized AAA rating in the first such downgrade of U.S. government debt in history. Now, the Chinese upstart is trying to attract foreign customers, promoting its own system that Guan says might serve emerging economies better than global agencies Moody's, S&P and Fitch.
