Japanese Prime Minister Shinzo Abe has attended a ceremony marking the anniversary of diplomatic ties between Japan and China and China's national day.

Abe attended the event at a Tokyo hotel Thursday, becoming a first Japanese leader to take part in the annual ceremony in more than a decade. He said he hoped Chinese President Xi Jinping will visit Japan at the earliest possible date.

The two Asian countries mark their 45th anniversary of ties on Friday, and China's national day is Sunday.

Abe told Chinese and Japanese guests that he hopes to visit China and improve relations further. Tokyo and Beijing have had rocky relations over Japan's aggression in World War II and disputes over uninhabited islands and undersea resources in the East China Sea.
