Why is there Germany in Iran's Six-Party Talks?
First of all, Germany is a big country in the European Union and has a decisive influence within Europe, which naturally affects the EU's decision-making on the Iranian nuclear issue. Secondly, Germany and Iran have a good relationship in history. For example, there are many Iranian expatriates in Germany now. On the other hand, many Iranian overseas deposits are in Germany. If the nuclear issue talks break down, there is still room for Iranian overseas deposits.
