The article is about an attack on a Chinese individual in Japan. The incident sparked high-level dialogue, and a government spokesperson, Mr. Lin, has demanded severe punishment for the perpetrator(s).
In Japan, the public safety is a highly valued aspect of life, and crimes, especially against foreign nationals, are taken very seriously. Political and diplomatic relations between Japan and China are historically complex, and incidents like these can stoke further tensions.
In the US or EU, assault on a foreigner also receives considerable attention and concern — not just for the crime's legality but its implications on international relations. Governments respond similarly, promising thorough investigations and adequate punishment for the perpetrators.
