On July 14, Iran and the P5+1 group of international mediators, comprising Russia, China, France, the United States, the United Kingdom and Germany, reached an agreement ensuring the peaceful nature of Tehran's nuclear program and easing sanctions against the country.
"The lifting of sanctions, I think, must take place as soon as possible, and the objective of our actions should be the implementation of the conditions outlined in the agreement," Burkhalter told the Neue Zuercher Zeitung newspaper.
He said the issue would be thoroughly considered by Swiss authorities but did not specify the dates for the sanctions lifting.
According to a draft document prepared by the P5+1 group and Iran last week, a new resolution to approve an agreement between international mediators and Tehran will replace previous decisions regarding the Iranian nuclear issue.
The resolution is up for voting in the Security Council on July 20.
