Chinese President Xi Jinping on Wednesday called on all countries to commit to mutual opening up that features shared governance.

"Faced with the challenges brought by economic globalization, we must not allow unilateralism or protectionism to undermine the international order and international rules," Xi said while delivering a keynote speech via video at the opening ceremony of the third China International Import Expo.

"Rather, we need to reform the global economic governance system in a constructive way to better seize opportunities and avoid harm," he said.

Guided by a vision of global governance based on extensive consultation, joint contribution and shared benefits, countries need to safeguard the multilateral trading system with the World Trade Organization as its cornerstone, improve the rules of global economic governance, and build an open world economy, Xi said.
