photo taken on October 1, 1984 show US President Ronald Reagan (R) and Chinese Premier Zhao Ziyang, both holding umbrellas, walking arm in arm, as Reagan escorts him to his car through the rain after a meeting in the Cabinet Room in the White House, Washington, D.C. The memoir of a top Chinese leader who was deposed over his sympathy with 1989 pro-democracy protesters has been published ahead of the anniversary of the bloody Tiananmen crackdown he tried to prevent.
