(Yicai Global) May 29 -- Shares of Gome Retail Holdings jumped after Chinese e-commerce giant JD.Com said it would buy USD100 million worth of the home appliances retailer’s convertible bonds as part of their deepening collaboration.

The Beijing-based pair's joint home appliance procurement will outstrip that of all others in China, The Paper reported.

Gome's shares [HKG: 0493] gained 5.5 percent today to HKD0.97 (13 US cents), their highest closing price since April 28, after earlier surging as much as 14.3 percent. The benchmark Hang Seng Index lost over 0.7 percent.

Last month, Gome also teamed up with e-commerce platform Pinduoduo. That partnership was also sealed with an investment of USD200 million in Gome's convertible bonds, which are securities that can be changed into common stock of the company.

JD.Com will provide Gome with products beyond the latter's usual scope, while Gome will expand JD's product offering. Its logistics unit Anxun Logistics will also help the e-commerce platform deliver and install the equipment, the report said.

The new plan solidifies the pair's partnership after Gome opened a flagship store on JD.Com, the latter said. The tie-up is in line with Gome’s efforts to integrate its physical stores, mobile application, and social media platforms to better serve clients, the retailer said.
