Hoss also announced that a trade delegation will arrive in Tehran next week to get familiar and evaluate conditions for economic relations with Tehran.
The Swiss envoy said expansion of economic ties with Iran is linked to a strong base in banking and financial transactions, Fars News Agency reported.
"Iran boasts of a huge potential for developing tourism industry and Swiss tourists are keen to visit Iran's historical and cultural attractions," he said.
Referring to the decline in bilateral trade exchanges from $3 billion three years ago to $500 million this year, he hoped that trade balance would witness remarkable growth once nuclear talks bear fruit.
Hoss also described Iran as a major, beautiful and influential country.
In July, Iranian Ambassador to Switzerland Gholamali Khoshrou and Swiss President Didier Burkhalter stressed the need for both Tehran and Bern to utilize their full capacity and potential to promote bilateral relations in all sectors.
At the meeting in Bern, Khoshrou also conveyed a message from President Rouhani to Burkhalter and voiced Tehran's enthusiasm for expanding mutual cooperation in all fields.
President Burkhalter, who is also the Swiss foreign minister, hoped that ties between the two countries would witness further expansion during Khoshrou's tenure.
