By Matthew Gertken and Jennifer Richmond Beijing has become noticeably more anxious than usual in recent months, launching one of the more high-profile security campaigns to suppress political dissent since the aftermath of the Tiananmen Square crackdown in 1989. Journalists, bloggers, artists, Christians and others have been arrested or have disappeared in a crackdown prompted by fears that foreign forces and domestic dissidents have hatched any number of "Jasmine" gatherings inspired by recent events in the Middle East. More remarkable than the small, foreign-coordinated protests, however, has been the state's aggressive and erratic reaction to them. Meanwhile, the Chinese economy has maintained a furious pace of credit-fueled growth despite authorities' repeated claims of working to slow growth down to prevent excessive inflation and systemic financial risks. The government's cautious approach to fighting inflation has emboldened local governments and state companies, which benefit from rapid growth.
