Citizens of Switzerland and of 50 other countries will be permitted visa free entry into China for short term stays of not more than six days, the Chinese State Public Security Ministry announced. Shanghai, Nanjing and Hangzhou have become the first cities in China to implement a 144-hour visa-free policy. The policy allows foreign visitors to arrive and depart from any of these three cities via airports, cruise terminals and train stations without a visa, providing their overall stay is within the six-day limit.
