Chinese firms wave the flag to cash in on Japan tension

SHANGHAI (Reuters) - The image of a small island topped by a massive Chinese flag that dominated the home page of Chinese internet giant Baidu Inc on Tuesday leaves little doubt as to where its allegiances lie.

Baidu and companies across the country are tapping a frenzy of nationalist sentiment, launching patriotic promotional campaigns as thousands take to the streets to protest against the Japanese government's purchase last week of some disputed islands from a private owner, islands China claims as its own.
