China's Vice-Premier Wang Yang delivering a speech at the 11th China-Northeast Asia Expo Opening Ceremony said: "Although China has run a trade deficit with several countries in the region, we do not engage in trade protection, and is willing to further expand our imports from these economies to meet diversified needs."
