Japan rejects China's demand for apology

Japan has turned down China's demand for a formal apology after releasing a Chinese fishing boat captain who was detained for two weeks in Okinawa.
Zhan Qixiong was arrested earlier this month after his trawler collided with two Japanese patrol vessels near disputed islands in the East China Sea.
Despite his release, the two countries remain locked in their worst diplomatic row for years.
Tensions were further heightened when China detained four Japanese this week.
The four who were working for a Japanese construction company were questioned on suspicion of filming in a military zone.
