SHANGHAI (REUTERS) - Alibaba Group Holding will buy e-commerce business Kaola from Chinese gaming company NetEase Inc for US$2 billion (S$2.7 billion), adding a platform that specialises in supplying luxury goods from abroad to Chinese consumers.

The long-rumoured deal comes as China's e-commerce players including Alibaba and JD.com Inc look to niche segments for growth, with the online shopping industry in the country slowing as economic growth eases.

While Alibaba's Tmall already allows overseas brands to launch and manage virtual storefronts on its platform, Kaola offers a more curated collection to wealthy clients, primarily purchasing goods directly from suppliers to resell to consumers.

Chinese consumers account for more than a third of the luxury goods sector's worldwide revenues.

"With Kaola, we will further elevate import service and experience for Chinese consumers through synergies across the Alibaba ecosystem," Alibaba CEO Daniel Zhang said.

Alibaba, along with private-equity firm Yunfeng - which is backed by the tech giant's founder Jack Ma, said it will separately invest about US$700 million in Netease's music streaming service, NetEase Cloud Music.

Kaola, launched by NetEase in 2015, aggressively targets shoppers in China, by offering products from brands such as Gucci, Shiseido and Burberry.

Kaola has an advantage over larger e-commerce players as it specialises in cross-border shopping, according to Ker Zheng, who tracks China's online retail sector at consultancy Azoya.

By offering a relatively narrow selection of popular items, it can boost bulk purchases from suppliers and offer low prices.

"Kaola does not have to share user time or basket space with cheaper, non-imported products," said Zheng, adding that this ensured them a loyal consumer base of wealthy shoppers.

Alibaba plans to let the Kaola app continue to operate independently under its current brand, while Tmall import and export general manager Alvin Liu will become Kaola's new CEO, the companies said in a statement.
