Guangzhou, Romanized as Canton in the past, is the capital and largest city of southern China's Guangdong Province. It's also one of the five National Central Cities at the core of the Pearl River Delta.

Thanks to its convenient geographical position, Guangzhou is often referred to as "China's Southern Gateway".

With an extensive history of 2,230 years, Guangzhou is the oldest port city and commercial center connecting with the outside world.

Covering an area of 7,434.43 square meters, the city has a registered population of 8.25 million, and is home to more than 16 million people.

A metropolis full of life, Guangzhou is one of only a handful of historical cities, national innovative cities, and civilized cities, and info-ports announced by the State Council.

The city has become a window for international exchanges with some 58 percent of information output transferring via Guangzhou to the rest of the world.

The city had a registered annual output value of 1.8 trillion yuan ($0.26 trillion) in 2015, ranking third among Chinese mainland cities for the 26th consecutive year.

Guangzhou is also a renowned international commerce hub, with its foreign trade value totaling 830.64 billion yuan in 2015, up 3.55 percent year-on-year.

The dynamic city also remains a magnet for international enterprises, with more than 10,000 foreign-funded enterprises setting up branches or subsidiaries in Guangzhou, 235 of which are Fortune 500 companies. 

Guangzhou also boasts a good business environment, and topped the Forbes list of Top of the Best Commercial Cities on the Chinese mainland for three years in a row, beating Shanghai and Beijing.

It is also southern China's key transportation hub and trading port. The passenger throughput of Guangzhou Baiyun International Airport ranks 16th among its global counterparts, while the volume of goods and containers traversing Guangzhou Port rank fifth and sixth, respectively.

Guangzhou’s unique charm radiates through its relationships with foreign cities. Currently, Guangzhou has 36 sister cities worldwide and has established international friendly cooperation relationships with 28 foreign cites. In addition, 55 countries have set up consulate-generals in Guangzhou.
