BEIJING—China is trying to tamp rising anti-Japan sentiment
after a weekend of sometimes violent demonstrations by
threatening to arrest lawbreakers and scrubbing websites of
protest-related images and posts.  At the Japanese Embassy in
Beijing on Monday, around 60 people protested Tokyo's claim to a
string of uninhabited islands in the East China Sea that Beijing
also claims. The protesters were far outnumbered by around 1,000
security personnel.  Protests flared in cities across China over
the weekend, with some violence and looting of factories and
shops. They were the largest anti-Japanese demonstrations since
2005.  More demonstrations were expected Tuesday on the
anniversary of the Mukden Incident, a bombing of a railway that
Japan used as a pretext to invade northern China in 1931.
