Starbucks shakeup aims to revive flagging fortunes

Coffee giant faces challenges from local brands as China sales fall

Starbucks Corp is planning to make "significant changes" to its organizational structure, while an industry expert said the coffee giant's new delivery services in China won't serve as a major boost.

According to a letter sent to employees by CEO Kevin Johnson, the restructuring, which could include corporate layoffs, is an attempt to combat the popular coffee retailer's falling sales and reignite investor interest, Bloomberg reported on Monday.
