Chinese Vice Premier Li Keqiang Monday called for international cooperation to deal with economic challenges and achieve common development.

Li made the remarks at a seminar here marking the 30th anniversary of China's cooperation with the World Bank. During his speech he urged nations to continue opening markets while removing trade and technology barriers.

Li reiterated China's stance on opening up and reform, pledging the country would continue to import advanced technologies, equipment, experience, talent and capital while creating a fair business environment for all enterprises.

China would protect intellectual property and grant foreign-funded companies equal treatment, Li added.

He also said China would step up the transformation of economic growth mode, which would rely on the nation's opening up and institutional reforms.

Li praised the World Bank's efforts on reducing poverty and said China would continue to support the World Bank to make new contributions to world development and prosperity.
