The most accurate comparison of how international events affected the responses of East Germany and China to the protests of 1989 would be:
The governments of both East Germany and China curtailed civil liberties and became less democratic following the protests of 1989, making both countries exceptions to the larger global trend of collapsing communist rule.
In context, East Germany experienced significant protests that were part of a broader wave of anti-communist movements in Eastern Europe, leading to the eventual fall of the Berlin Wall. However, despite the surrounding changes, East Germany's government initially crack downed on dissent before ultimately collapsing. Conversely, China responded to the Tiananmen Square protests with a brutal suppression, maintaining a strong grip on power and civil liberties, which represented a departure from the global trend towards democratization seen in many other communist states during the same period. Both governments' responses reflected a conservative tightening of control rather than an embrace of reform or liberalization, aligning them against the prevailing international currents of the time.
