According to a report by Swiss Info, the Swiss government has its eyes on talks with Washington on a free-trade agreement. The two countries will decide whether or not to enter into negotiations for a free-trade agreement in early 2006.
The report in short states an extremely valuable deal for both sides would be had. Industries which would profit the most from a free-trade agreement with the US would be the Swiss watch industry as well as the pharma- and chemicals industries.
One basic problem is with Swiss farmers who fear an open the domestic market could lead to cheap imports of US cereals, maize or rice. On the flip side the US is quite critical of Swiss agricultural subsidies. I'm sure there's more considering the way they have treated Canada with it's cattle.
