China and Switzerland launched a feasibility study on a free trade agreement in November last year.
Li said the two sides should press ahead with the feasibility study and get ready to launch negotiations as soon as possible.
The Chinese leader called for a deepened financial cooperation in order to contribute to the world's financial system reform and a comprehensive recovery of the world economy.
Cooperation on energy conservation and environment protection should be further strengthened to make it one of the shining points of the trade and economic ties between China and Europe, he said.
Cooperation in the field of high and new technology and that between small and medium-sized enterprises of the two countries should also be further deepened, he said.
Li said the trade and economic cooperation between China and Switzerland is embraced with a new starting point after 60 years of diplomatic ties between the two countries. He called on both sides to take the chance to bring an even better prospect for Sino-Swiss trade and economic cooperation.
Li arrived here on Monday for a four-day visit to Switzerland. He will also address the annual meeting of the World Economic Forum in the Swiss ski resort of Davos on Thursday.
