BEIJING — China will unswervingly advance opening-up to cover more fields in a broader scope and at a greater depth, a spokesperson for the 20th National Congress of the Communist Party of China said Saturday.

Pursuing high-level opening-up is an inherent part of the new development paradigm, spokesperson Sun Yeli told a press conference ahead of the opening of the congress.

Fostering a new development paradigm with domestic circulation as the mainstay and domestic and international circulations reinforcing each other will generate lasting momentum for the long-term development of the Chinese economy as well as the steady recovery of the world economy, said Sun.
