A new online video game has just been released in China which invites players to fight Japan over a group of islands whose sovereignty is disputed by the Chinese and Japanese governments.
The islands are known as the Senkaku in Japan and the Diaoyu in China and millions of gamers have already registered to play "Glorious Mission".
The game follows a wave of anti-Japanese sentiment in China as BBC East Asia editor Charles Scanlon explains.
