A McDonald's sign outside its outlet in China's Shenzhen
A McDonald's sign is displayed outside its outlet, the first one which opened in China in 1990, at the southern Chinese city of Shenzhen neighbouring Hong Kong March 18, 2013. McDonald's Corp gave away more than a million breakfast McMuffins across China on Monday, a few days after Chinese state television aired its annual expose on corporate malpractice to mark World Consumer Rights Day. The promotion, the U.S. fast food chain says, was purely coincidental. REUTERS/Bobby Yip (CHINA - Tags: FOOD BUSINESS LOGO POLITICS SOCIETY)
