China will further boost the development of e-commerce, aiming to bring online retail sales up to 10 percent of the country's total retail sales by 2015, according to guidelines released by the Ministry of Commerce on Thursday.

Total e-commerce transactions in China, including retail sales, are expected to exceed 18 trillion yuan ($2.95 trillion) by 2015.

By that year, exports and imports via e-commerce could amount to at least 10 percent of China's total trade, the ministry has forecast.
