Tim Cook visited China this week to discuss customer privacy with government officials, but as the Apple CEO's trip comes to a close, it's clear he did a lot more than that. According to the state-owned Xinhua News Agency, Cook also visited a Foxconn factory and promoted both Apple Pay and Apple Watch ahead of their official release in China.

Apple Pay is already live in the U.S., but bringing the service to China could be tricky. Cook says he still needs to figure out how to bring Chinese banks, merchants and local networks into the picture. Still, he's bullish it will be a hit once it does launch. "I'm convinced there will be enough people that want to use it," Cook said. "It's going to be successful."

Cook also believes the Apple Watch could be a big seller in China, though the company's first wearable device won't actually launch until early next year. "We are going to wonder how we ever lived without it," he said, "That's the real test of a great product… And I think that's going to happen to the Apple Watch."

Earlier in his trip the Apple CEO noted that it's only a "matter of time" before China becomes the company's biggest market. Apple recently announced that it plans to open an additional 25 Apple Store locations in China, bringing the total to 40, in a bid to increase its retail presence, which will certainly help it gain more traction.
