Some U.S. giants are stepping into the health care industry to provide medical services for their own staff. Amazon announced in late January that I will join hands with Warren Buffett's Berkshire Hathaway and JPMorgan to set up medical company that provides medical services to a total of about 1.2 million U.S. workers. Since then, Apple also plans to open health clinic chain for employees and their families this spring, AC Wellness. The practice of these U.S. giants is similar to the business enterprises' social responsibility in China.
