China's overall tariff level fell from 9.8 percent to 7.4 percent over the past five years, according to a government work report submitted to the national legislature for deliberation on Sunday. 

China remained committed to opening up wider to the world and expanded international economic and trade cooperation to deliver mutually beneficial outcomes, the report said. 

The country has developed new forms of foreign trade, building 152 new integrated pilot zones for cross-border e-commerce and supporting the establishment of overseas warehouses, it said.
