Chinese Internet giant Tencent, which is best known for its wildly popular messaging service WeChat (known as Weixin in China), has officially combined its e-commerce operations with online retailer JD.com, after rumors last month hinted at such a move.

The two companies have inked a strategic partnership that will see JD tap on Tencent’s significant mobile and Internet user base — WeChat, for example, has 272 million monthly active users – and Tencent will be able to leverage on JD’s e-commerce services. As part of their cooperation, Tencent will support JD in its e-commerce business by offering priority access points in its chat platforms, WeChat and mobile QQ, as well as provide support from other key platforms.

Tencent will initially hold a 15 percent stake in JD upon the completion of this deal, which Bloomberg pins at $214.7 million, and it will further subscribe at IPO price for an additional 5 percent of JD on a post-IPO basis. JD just filed for a $1.5 billion IPO in January this year.

In the meantime, JD will acquire 100 percent interests in Tencent’s e-commerce businesses — including QQ Wanggou and Paipai marketplace, logistics assets and personnel, as well as a minority stake in Tencent’s e-commerce site 51Buy.com (known as Yixun in China).

Both companies will also cooperate on online payment services, as they seek to improve the online shopping experience of customers. WeChat in China has already integrated payment options, and the partnership will no doubt give more emphasis to that.

Martin Lau, the president of Tencent, says: ” Our strategic partnership with JD will not only extend our presence in the fast-growing physical goods e-commerce market, but also allow us to better develop our enabling services such as payment, public accounts and performance-based advertising network to create a more prosperous ecosystem for overall e-commerce activities on our platforms.”

Tencent has been thirsty for success in e-commerce as it seeks to tap on its large userbase from its social platforms, especially WeChat, seeking to come up against Chinese e-commerce giant Alibaba.

A combination of Tencent and JD’s e-commerce businesses will no doubt lead to a stronger push for e-commerce on WeChat. It’s still an early start to the year, but Tencent has already been taking steps to boost its e-commerce presence on WeChat via a $50 million investment in ‘China’s Yelp’ announced yesterday, as well as a logistics deal last month.

Tencent and JD’s partnership can be viewed as waging war on China’s e-commerce stalwart Alibaba — and it will pose a huge threat to the latter, which is already stepping up its mobile social efforts. Alibaba’s CEO Jonathan Lu has pledged to continue the e-commerce giant’s string of big investments as it continues focusing on improving its services for mobile – and the company has launched mobile games and upped efforts to promote its chat appwoo mobile shoppers with free data and even give away free smartphones to retailers in China.
