Shanghai and neighboring Jiangsu & Zhejiang provinces will offer a 144-hour, or six-day visa-free transit, for foreigners from 51 countries on arrival in Shanghai, Nanjing or Hangzhou from January 30.
This means a business traveller could fly from Sydney to Shanghai or Nanjing, remain there for the business week, fly onwards to Hong Kong and then fly home - all without a Chinese visa - as Hong Kong is considered a separate country under China’s visa-free rules, making your Shanghai visit a ‘transit’.
