Chairman Xi Guohua and Cook discussed “cooperation” at China Mobile’s headquarters in Beijing today, the carrier said in an e-mailed statement. It didn’t elaborate. Apple’s Beijing- based spokeswoman Carolyn Wu didn’t immediately return calls.

Cook is making his second visit to China in less than a year as Apple tries to reverse its shrinking share of the local smartphone market. The company’s growth in the world’s most populous nation has been limited by it only working with smaller carriers and by competition from domestic phone-makers.
