A Japanese destroyer steamed into a southern Chinese port today (Tuesday), the first such visit since World War Two.
The warship Sazanami pulled into Zhanjiang in the southern province of Guangdong for a five-day port call, following the visit of a Chinese naval missile destroyer to Japan in November.
The countries have recently been making efforts to improve relations. Chinese President Hu Jintao paid a state visit to Japan in May.
But, Japan's offer to transport relief supplies on a military flight to victims of China's May 12th earthquake was rejected after Chinese Internet users reacted angrily to the proposal.
Japan invaded and occupied China from 1931 through 1945, and relations are still marred by memories of Japanese wartime atrocities.
