The historical background of the establishment of diplomatic relations between China and Germany is somewhat special. At that time, Germany was divided into two parts: Democratic Germany and Federal Germany. New China was founded in 1949, China established diplomatic relations with the then Democratic Germany in 1950, and the Federal Republic of Germany also established diplomatic relations with China in 1972, which was not a problem at that time. The problem came later: the historical process soon reached 1990 10. This year, the Berlin Wall was demolished, Germany and Germany were unified, and the former Democratic Germany ceased to exist. All the original rights and obligations were inherited by the former Federal Republic of Germany. The date of the establishment of diplomatic relations between China and Germany is still controversial, and historians have their own opinions. Some people think that the date of the establishment of diplomatic relations between China and GDR should prevail. Some people think that since the former GDR and present Germany have a continuous and inherited relationship, and the former Federal Republic of Germany is the main body, then the 1972 when the Federal Republic of Germany established diplomatic relations with China should prevail. The views of the two factions are roughly evenly matched, and no one can convince anyone. It seems that this is a matter of opinion.
