Tim Cook paid a visit to Foxconn's iPhone manufacturing plant in Zhengzhou today, one of what could be many stops during his China trip. The Apple CEO tweeted out "Great to meet talented like Zhang Fan, who helps make iPhone 6 in Zhengzhou," along with a photo.
Cook's face is a familiar one at many Asian supplier factories, thanks to his long tenure as Apple's operations chief and the company's recent commitment to comply with Fair Labor Associations guidelines. In fact, he visited the Zhengzhou plant as recently as spring 2012.
