Apple has officially made it big in China. Sales of Apple devices in China hit $16.8 billion in the second quarter, up 71% year-over-year, according to Apple’s Q2 earnings release published Monday. Chinese sales now account for nearly 30% of Apple’s total revenue. Much of that growth in what Apple refers to as “Greater China,” which includes China, Hong Kong and Taiwan, comes from the recent release of the iPhone 6 and iPhone 6 Plus.
