From the Middle Kingdom:

BEIJING — Apparently unnerved by an anonymous Internet campaign urging Chinese citizens to emulate the protests that have rocked the Middle East, Chinese authorities this week have begun a forceful and carefully focused clampdown on activities by foreigners that the government deems threatening to political stability….
In Shanghai, the authorities objected to the location of an annual St. Patrick’s Day parade set for March 12 that had been expected to draw more than 2,000 people, prompting Irish organizations to abruptly cancel the event on Monday. The parade was to have taken place on a major street close to a cinema where the Internet postings had urged people to gather every Sunday to show their displeasure with the Chinese government.
