Small, moutainous and wealthy, with a population of just 7.5 million, Switzerland is well-known for its enviable quality of life in a country that ticks along like clockwork.. Its products are sought all over the world, from its delicious cheese and chocolate to luxurious watches whose timekeeping is as sharp as a Swiss Army Knife, another popular export from this Alpine ( 高山的，阿尔卑斯的 ) nation.

Switzerland’s famed political neutrality ( 中立的 ), financial power and isolated location, which is ring-fenced by breathtaking mountains, have enabled it to play a safe but central role in European affairs. The conveniently central locationin tne middle of Europe has also made Switzerland a favourite meeting place for conventions and international conferences – Geneva, for instance, is the headquarter of the United Nations.

Switzeriand is not only a place for professionals, though. As a stylish tourist detination it offers such top ski resorts as Zermatt, Verbier and celebrity-studded (名人云集的) St Moritz, while the white peaks of moutaina set against blue skies make a wonderful backdrop for summertime hiking. The ancient capital of Berne provides　 superb opportuinties for sightseeing, shopping and traditional folk entertainment while the largest city, Zurich leads the way in arts, design and nightlife, from opera and world-class theatre to stylish bars and nightclubs.

Switzerland’s unique political model is based on consensus-building, and considering that the country consists of several culturally different groups speaking different language ( Swiss German, French, Italian and Romansh), its peaceful domestic situation is admirable. And while the Swiss in practice have been neutral in foreigh affairs for several centuries, they are increasingly willing to get more involved in world affairs and distribute the skills in democracy and diplomacy they have developed domestically on the international stage. Switzerland finally joined the United Nations in 2002, and signed the Schengen treaty in 2005, showing their support for the European Union.
