In January 1987, as part of Deng Xiaoping's crackdown on "bourgeois liberalism," Liu Binyan was again expelled from the Communist Party. In spring of 1988 he came to the United States for teaching and writing; then, after publicly denouncing the Chinese government for the Tiananmen Square protests of 1989, he was barred from returning to China and never saw his homeland again. Although largely isolated from his Chinese readers, he continued to write about China where his sources often came from interviewing visitors from China.
