Dubai's Burj Khalifa, the tallest building in the world, was lit up to support China

The Burj Khalifa in Dubai was lit up with the image of the flag of the People's Republic of China to show support for the country as it fights to contain the outbreak of the Wuhan coronavirus.
The 2,716.5-foot-tall building (more than 828 meters) also displayed the phrase "add oil," a common refrain in Chinese used to mean "keep going."
