Covering just 1,106 square kilometers with a population of more than7.3 million, Hong Kong ranks as one of the world's most densely populated cities. To make the full use of limited space, the city has over 1,300 skyscrapers, far more than other world metropolises such as Tokyo (about 490) and New York City (about 730). As the city marks the 20th anniversary of its return to China, Matthew Cheung Kin-chung, Chief Secretary for Administration in Hong Kong, said Hong Kong will make great endeavors to continue as a dynamic, green and low-carbon city for life and work.
