Washington must shake off its Cold War mentality

Editor's Note: November 9 marked the 30th anniversary of the fall of the Berlin Wall, which had not only divided the Federal Republic of Germany and the German Democratic Republic, but also divided the East and West during the Cold War. Its fall symbolized the end of the Cold War. Beijing Youth Daily comments:

While looking back at this historic moment, people should focus more attention on the new phenomenon that some invisible or tangible walls are being built.

In Germany itself, the development gap between the east and the west is still evident, and the development in the east has seemingly come to a standstill, with only 7 percent of Germany's 500 most valuable companies based in the east. In other words, there is still an invisible wall of social and economic development within Germany.
