What's more, within China, Apple is facing lower-priced competition by the likes of Samsung, Huawei, Xiomi and ZTE.
Phones offered by Apple's Chinese competitors are both packed with features and sell at a fraction of what an iPhone sells for in China.
The ongoing US-China trade war will also impact the broader global economy. The German, South Korean and Japanese economy provide important inputs and supplies to the Chinese manufacturing economy.
When Foxconn assembles an iPhone in China, many of the parts that go into the iPhone are imported from South Korea, Japan and Germany. Thus, a slowdown in China will infect other parts of the global economy.
