Describing Switzerland's role in the tensions between Iran and the United States, he said, " You can make mistakes in life and that is part of it. However, two things must be avoided: The first is to have high expectations because the world changes, but humans do not change in five minutes. The second is to take actions that destroy trust."

We are celebrating one hundred years of diplomatic relations which is still based on trade and peace, he said.
