The responses of East Germany and China to the protests of 1989 can be understood in the context of how international events influenced their actions.
In East Germany, the protests were part of a broader wave of anti-communist sentiment sweeping through Eastern Europe, with countries like Poland and Hungary experiencing significant political changes. This external influence made it increasingly difficult for the East German government to justify its repressive measures, leading to a more significant public outcry for civil rights and, ultimately, the fall of the Berlin Wall. The pressure from neighboring countries and a growing perception of an inevitable collapse of the communist regime motivated the East German government to allow for some degree of reform and eventual reunification with West Germany.
In contrast, China's response was shaped by its relative isolation from this broader trend of reforms in Eastern Europe. While there were protests in China, particularly at Tiananmen Square, the Chinese government was able to maintain a firmer grip on power, enforcing a harsh crackdown despite the global wave of democratization. This isolation allowed the Chinese leadership to disregard the international call for reforms, instead reaffirming its commitment to maintaining strict control and limiting civil liberties.
In summary, East Germany's response was influenced by its proximity to successful anti-communist movements and a resultant pressure for reform, while China's isolation allowed it to respond with repression, despite the global context urging democratization.
