Chinese paramilitary policemen stand under an umbrella in front of the giant portrait of Chairman Mao Zedong on Beijing's Tiananmen Square June 2, 2009.

China's economy is now the third-largest in the world, an achievement that would have been unthinkable during the impoverished 1980s. But political reform has stalled, with the Party quick to stamp out any perceived challenge. REUTERS/David Gray (CHINA CONFLICT POLITICS)
