A Fragile Relationship

President Nixon's historic trip to China in February 1972 marked the beginning of a new era in Sino-American relations. For the first time since 1949, the two countries established high-level official contacts and transformed their relationship from confrontation to collaboration. Over the subsequent twenty years, however, U.S.-China relations have experienced repeated cycles of progress, stalemate, and crisis, with the events in Tiananmen Square in June 1989 the most recent and disruptive example. Paradoxically, although relations between the two countries are vastly more extensive today than they were twenty years ago, they remain highly fragile.
