Shanghai is destined to be a highly influential city in global commerce, finance, culture and tourism in the near future. It is China's most populous city, even without including the thousands of tourists visiting this summer. If you have a chance to travel to this global city, here are a few things you do not want to miss:

Expo

This summer is a great time to visit Shanghai because the city is hosting Expo 2010 until Oct. 31. With more than 190 countries participating with self-designed and self-run pavilions, this is the largest and most expensive World Expo ever. An all-day ticket to the Expo costs 160 RMB (not including holidays) and is more than worth the money. To avoid the crowds and the heat, arrive late in the afternoon and stay until the Expo closes at midnight. Each pavilion is special, but the larger pavilions (consequentially the ones with the longer lines) tend to have the more interesting and interactive exhibits. Don't miss the amazing authentic food and beverages from your favorite countries, such as Belgian beer and Korean cuisine.
