In an interview with Xinhua, Mr Chen said China's retail sales of consumer goods this year will exceed CNY15 trillion (US$2.25 trillion), of which CNY450 billion (US$67.53 billion) will be spent via online shopping.
In the first 11 months of the year China's foreign trade surged 36.3 per cent year on year to US$2.677 trillion, according to the latest customs figures.
Retail sales from January to November hit CNY13.92 trillion (US$2.1 trillion), representing an increase of 18.4 per cent compared to the same period last year.
With regard to China's 12th Five-year Plan which covers the period from 2011-2015, Mr Chen said the ministry would aim to make its trade and international payments more balanced, in order to create a better investment environment to attract high-end international capital.
He was cited as saying the next five years would be a crucial period for Chinese enterprises to invest overseas.
"The country encourages competitive enterprises to go global with efficient risk-control measures," he said. "We will give them more public service and more effective legal protection in this regard."
Mr Chen said China's outbound direct investments in non-financial sectors are expected to top US$50 billion this year. "I estimate the proportion will be much higher in the future," he said.
To spur the use of clean and fuel-efficient cars, Beijing reduced the car-buying tax and has been handing out vehicle trade-in subsidies since 2009. Such measures are due to expire by the end of this year.
But the report said the ministry would continue offering vehicle trade-in subsidies for the sake of environmental protection rather than focus on just boosting auto sales, he said.
