Chinese President Hu Jintao on Saturday urged Japan to reflect on its World War II aggression and back up its apologies with action, after meeting with Japanese Prime Minister Junichiro Koizumi in a bid to ease tensions between the two Asian powers.

In a rare public statement, Hu also demanded that Tokyo not support any moves toward independence by Taiwan, saying it was key to good relations between Japan and China.
