The road of global economic recovery has been bumpy in the wake of the 2008 global financial crisis, said Vice-Premier Zhang Gaoli on Sunday.

Structural reform is needed to solve the deep-rooted problems of the world economy, he told participants of the China Development Forum.

He said China has made relentless efforts to reform its economic structure and contribute to global economic recovery, Zhang said, adding that China contributed to about 30 percent of world growth in 2016 while contribution of Asia as a whole was about 50 percent.
