The stabbing is the second violent incident targeting Japanese school students in China in the span of three months. On June 24, a man attacked a Japanese school bus in the eastern city of Suzhou, Jiangsu Province, killing a Chinese bus attendant, who attempted to save the students, and injuring two others.

Japan's ambassador to Beijing has asked for more security for Japanese nationals in China after a 10-year-old Japanese boy was killed this week in a knife attack that was the second to target school students.
