China's leader-in-waiting Xi Jinping has warned Japan to "rein in its behaviour" and stop undermining Chinese sovereignty, according to state media reports.
His comments follow days of sometimes violent anti-Japanese protests in China over a chain of disputed islands in the East China Sea.
Mr Xi made the remarks during a meeting with US Defence Secretary Leon Panetta who is currently in Beijing as part of a regional tour.
