BEIJING, Aug. 29 (Xinhua) -- Chinese Vice Premier Liu Yandong here on Tuesday expressed the expectation that youth exchanges would inject positive energy into Sino-Japanese ties.

She made the call at a friendship exchange meeting of 1,000 university students from China and Japan at Peking University.

She encouraged students to learn from history and look into the future, cherish opportunities to cultivate friendship and mutual understanding, and to cement relationships.
