China is not the source of risk of the world economy, but one of the engines that is pushing its growth, said Premier Li Keqiang at the opening ceremony of 2015 Summer Davos forum.

The steady growth of Chinese economy also benefits the world, as the country contributed about 30 percent to the growth of world economy in the first half of this year, said Li.
