Chinese e-commerce giant Alibaba Group Holding Ltd (BABA.N) is unlikely to be interested in buying Yahoo Inc's (YHOO.O) core business, the Wall Street Journal reported. Yahoo's board, in a three-day meeting that started on Wednesday, is weighing a sale of the company's Internet business, Reuters reported on Tuesday, citing a person familiar with the matter. Board members are also expected to discuss the details of the planned spinoff of Yahoo's 15 percent stake in Alibaba, worth more than $30 billion. Alibaba will be interested in repurchasing its shares from Yahoo only at a steep discount, the WSJ said on Thursday, citing a person familiar with the matter. (on.wsj.com/1jAjb0T) Alibaba and Yahoo were not immediately available for comment.
