According to AP :The U.S. has demanded to see a Swiss contract for natural gas supplies from Iran to see whether it violates an American sanctions law against Tehran, the U.S. Embassy in Switzerland said.

“At this time, the Swiss have a mandate as our protecting power in Cuba and Iran,” the Web site said in response to a “frequently asked question” on whether the Swiss role was “in jeopardy.”

The embassy reiterated that the U.S. had told the Swiss “that major new oil and gas deals with Iran send precisely the wrong message” to Iran when it is defying U.N. Security Council resolutions and the efforts made by the 5+1 countries over its uranium-enrichment program.

A posting on the U.S. Embassy Web site Sunday raises the question of whether neutral Switzerland’s position as representative of American interests in Iran and Cuba could be affected.
