The Sazanami is carrying supplies for victims of the Sichuan earthquake
A Japanese warship has arrived in southern China for a five-day port call, the first such visit by a Japanese navy ship since World War II.
The Sazanami sailed into port in the city of Zhanjiang seven months after a Chinese warship, the Shenzhen, visited Japan.
The reciprocal port calls were agreed at a meeting last year between senior military figures from the two nations.
This one comes amid improvements in the often tense China-Japan relationship.
Earlier this month, the two sides struck a deal to jointly develop gas fields both claim in the East China Sea, resolving a protracted bilateral dispute.
That agreement followed a visit to Japan in May by Chinese President Hu Jintao, the first by a Chinese leader in a decade.
'Friendship and trust'
Chinese state television showed pictures of the Sazanami, a destroyer, arriving in port.
The Japanese vessel is carrying relief supplies for the victims of last month's Sichuan earthquake.
The crew will hand over 300 blankets, more than 2,500 pre-packaged meals and hygiene masks during their stay.
Chinese foreign ministry spokesman Liu Jianchao rejected the idea that the visit could ignite lingering anti-Japanese sentiment.
The visit would "help enhance the friendship and mutual trust between the two countries", he told a news conference in Beijing.
