Dubai expects 25 million people to visit World Expo
The World Expo is opening in Dubai, and its organisers hope it will attract millions of overseas visitors to the emirate.
World Expos allow countries showcase their latest technology, and they've been drawing in crowds for the past 170 years dating back to Queen Victoria's reign. But visitor numbers for this year's Expo may be lower than usual due to Covid as many countries are still putting restrictions on international travel.
