Apple CEO Tim Cook Joins Weibo, China's Answer to Twitter

Apple CEO Tim Cook has repeatedly emphasized the company's focus on China as a new source of growth. He doubled down on that sentiment recently — by joining Weibo, a micro-blogging service that is similar in many ways to Twitter. The verified account displayed a message from Cook on Monday that read, in English and Chinese, "Hello China! Happy to be back in Beijing, announcing innovative new environmental programs." The note was a reference to Apple's Monday announcement regarding clean energy and environmental protection initiatives in China.
