30 years after Tiananmen, US says hopes dashed as China defends crackdown

The United States said Monday it had lost hope for human rights progress in China 30 years after the crackdown on Tiananmen Square as Beijing, in rare official comments on the bloodshed, insisted it had "immunized" itself against turmoil."Over the decades that followed, the United States hoped that China's integration into the international system would lead to a more open, tolerant society.
