Despite weaker domestic and global demand, China's economy managed to grow almost 7 percent in 2015, supported by employment and household income, according to Chinese Premier Li Keqiang.

During the official launch of the China-backed Asian Infrastructure Investment Bank (AIIB), Premier Li said China remains one of the world's fastest-growing major economies after expanding more in 2015 than in 2014.

The premier added that the country's gross domestic product (GDP) is around US$10 trillion, with the services sector taking up almost half of last year's total GDP.

"Our GDP of year grew by around 7 percent or, in other words, nearly 7 percent," Li said.

Premier's GDP figure was higher than what analysts predicted for 2015. According to a survey conducted by Reuters, analysts believed the Chinese economy cooled to 6.9 percent last year from 7.3 percent in 2014.

A 7 percent growth or lower, however, will be the weakest annual growth for the country in about 25 years.

Li, who spoke before a gathering of foreign and Chinese delegates to the AIIB in Beijing, issued the comment ahead of the scheduled release of the official data for the fourth quarter and for the entire 2015 on Tuesday.

Premier Li also revealed that employment in China expanded more than what was expected after more than 900 million people getting into the country's workforce last year, with 150 million of them considered as skilled professionals.

China's work force, Li added, will continue to help shift the Chinese economy to one built on human resources from one built on natural resources in pursuit of a medium to high growth rate.
