Chinese e-commerce powerhouse Jingdong Group will build an e-commerce industrial park in a north China city as a regional integration plan gains steam.

The business park, the biggest of its kind in China, will be located in Langfang City, Hebei Province. It will be built with Jingdong's investment, technology and human resources, while the Langfang government will help with infrastructure, according to a memorandum inked on Sunday.

The park will serve as an important logistics center for Jingdong Group, while Langfang hopes it will boost the city's e-commerce development.

The two also agreed to cooperate in government purchasing.

Jingdong Group is a major e-commerce player in China, with its subsidiary JD.com accounting for 25.1 percent of the country's online business-to-consumer market during the first half of this year, second only to rival Tmall under Alibaba at 57.7 percent, according to China e-Business Research Center.

China is encouraging the Beijing-Tianjin-Hebei integration program, with Chinese Premier Li Keqiang saying on Saturday that the plans should be accelerated to explore growth potential.
