Due of growing geopolitical threats and a sluggish economy, Apple is having a number of problems in China.
Analysts believe that a resurgent Huawei following a rumoured significant semiconductor breakthrough that defied U.S. sanctions will be the biggest threat of all.
Washington has expressed alarm over the newest chip produced by SMIC, the largest semiconductor maker in China, and has questioned how it was possible without access to key technologies.
But there is also concern over whether the manufacturing process for these new chips is effective enough to support a Huawei comeback on a wide scale.
