Historic port call marks Japan-China thaw(Read article summary)
The arrival of a Japanese war ship in a Chinese port and the recent announcement of a joint gas-exploration deal signal improving bilateral ties, but territorial disputes remain unresolved.
The visit comes on the heels of a landmark deal last week between Tokyo and Beijing to jointly develop gas fields in the East China Sea, and an ice-breaking visit by Chinese President Hu Jintao to Japan in May.
Analysts see these events as part of a broad trend of warming relations between the historic rivals. But they cautioned that the two nations have failed to resolve dangerous, underlying disputes in the East China Sea.
