Apple CEO vows to beef up investment

Apple Inc CEO Tim Cook is on a trip to China this week, pledging to boost investment in Shanghai and strengthen communication with local mobile app developers.

The move, amid the ongoing Sino-US trade frictions, underlines the importance of China, the world's largest mobile arena where Apple is locked in competition with rivals such as Huawei Technologies Co Ltd.

In a meeting with Shanghai Party Secretary Li Qiang on Tuesday, Cook said the US tech heavyweight will invest more in Shanghai and actively seek to expand cooperation, according to a report by Shanghai media.
