The German Minister of State for Culture, Bernd Neumann, praised Gorbachev for his role in bringing about German unity in a speech in the port city of Bremen. Neumann said without Gorbachev's readiness for change, German unification would not have been possible.
Gorbachev, who turned 75 on March 2, replied by calling on Germany to help Russia, saying cooperation between the two was indispensable for a stable Europe.
Gorbachev is celebrated as a hero in Germany for helping to bring about the country's unification in October 1990.
