The Burj Khalifa Since 2010, the Burj Khalifa in Dubai has held the title of world's tallest structure at 2,716 ft. The Vincom Landmark 81 tower in Ho Chi Minh City, Vietnam, is the smallest structure on the list, standing at 1,513 feet. Only one US tower, New York City's One World Trade Center, made the top 17. The Empire State Building, currently under renovation since 2012, was once again crowned as the world's tallest building during its reopening in 2014.
An answer to this question could be found by looking at the list of current and former world's tallest buildings. However, such a list changes so frequently that it is not useful for answering this question. For example, some people might argue that the Tower of David in Jerusalem is even taller than Two World Trade Center. But because this building was never completed, it cannot appear on any official lists.
The best way to answer this question is to look at the actual height of the building. The Burj Khalifa is 828 m (2,716 ft) tall while the Empire State Building is 1,250 m (4,094 ft) tall. This means that the Burj Khalifa is actually more than twice as tall as the Empire State Building!
New York City has been home to three of the four tallest buildings in the world. The fourth is now under construction in Dubai and is expected to be completed in 2020. It will be almost two miles high!
Since 2010, the 828-metre (2,717-foot) tall Burj Khalifa in Dubai has held the title of tallest building. The Burj Khalifa has been designated as a "megatall," or the world's tallest structure.

The Burj Khalifa At 829.8 meters, the Burj Khalifa skyscraper is the world's tallest building (2,722 ft). Guyed masts (such as telecommunication masts), self-supporting towers (such as the CN Tower), skyscrapers (such as the Willis Tower), oil platforms, electrical transmission towers, and bridge support towers are among the structures included. The list below includes only those that are actually used for telecommunications purposes.
The dominance of this one country has made me wonder about other countries where it can be done differently. China has an incredible amount of need for more communications infrastructure, especially given their population size. However, because of government regulations, most Chinese telecom companies must have their equipment installed by their local partners, which usually means importing some kind of foreign technology.
In fact, according to a report from Cisco Systems, China will be the world's leading country for mobile data traffic by 2014. But most of that traffic will be carried by American companies like Verizon and AT&T due to the lack of domestic competition.
India also needs more communications infrastructure, but they have many local manufacturers who would like to break into this market. In addition, India has some very remote areas where there is no communication at all. A project called "Mission Bhartiyo" aims to provide wireless Internet service to 500 villages by 2020.
Africa also has some very poor communication conditions with very few people having access to phones or Internet.
The world's tallest building, at 2,723 feet (829.84 meters), is the Burj Khalifa (previously Burj Dubai) in Dubai, United Arab Emirates. The second tallest building, by volume, is the CN Tower in Toronto, Canada.
The third tallest building, by height, is the Shanghai World Financial Center, which is currently under construction. When it is completed in 2016, it will be the first building in the world to top out at 3,556 feet (1,073.5 meters).
The fourth-tallest building is the Petronas Towers in Kuala Lumpur, Malaysia. They are each 1,453 feet (442.5 meters) tall, making them the most powerful pairing of towers on Earth with both being over 1 mile (1.6 km) high.
The fifth-tallest building is the Pompidou Centre in Paris, France. At 1,020 feet (305.5 meters), it is less than half the height of the Petronas Towers but still holds the title of the highest occupied building in Europe.
The sixth-tallest building is the Jianguomen Tower in Beijing, China.
