Dec 6 (Reuters) - Alibaba Group Holding Ltd (9988.HK) said on Monday it was reorganising its international and domestic e-commerce businesses and would appoint a new chief financial officer. The changes come as Alibaba faces headwinds on multiple fronts, including increased competition, a slowing economy and a regulatory crackdown. Alibaba said it would form two new units to house its main e-commerce businesses - international digital commerce and China digital commerce, in a bid to become more agile and accelerate growth. The international digital commerce unit will house Alibaba’s overseas consumer-facing and wholesale businesses, and include AliExpress, Alibaba.com and Lazada. The unit will be headed by Jiang Fan, whose had been president of the Taobao and Tmall marketplaces. Alibaba will house its domestic commerce businesses in the China digital commerce unit which be led by Trudy Dai, a founding member of Alibaba, it said.
