Special Administrative Regions
Hong Kong
The government of Hong Kong started reclaiming land from the surrounding sea as early as the 1840s. Formal reclamation starts at 1860s and its land reclamation is still proceeding. A notable achievement is Hong Kong International Airport, built in the 1990s on reclaimed land, absorbing the former islands Chek Lap Kok and Lam Chau.
The Shenzhen river (between Hong Kong and mainland China) has been channelised through land reclamation projects.
Macau
Macau has been the site of land reclamation projects for several hundred years. As of 2023, more than half of Macau is composed to reclaimed land.
Macau's Cotai Strip was built upon a 5.2 square kilometer land reclamation site in the Seac Pai Bay of the Pearl River Estuary. The strip joins the formerly separate islands of Taipa and Coloane. The Cotai Strip is a gambling and shopping area which includes a dozen multibillion-dollar resorts, a private university campus, and the Macau garrison of the People's Liberation Army.
South China Sea
In the 21st century, the PRC has upheld the 1947 claims of the Republic of China (modified by Zhou Enlai into a nine-dash line) over most of the South China Sea through a series of disputed mid-ocean land reclamation projects in the Spratly Islands known as the Great Wall of Sand. China was motivated to begin land reclamation projects in the Spratlys because it had relatively little land in the area.
The islands being expanded or created by the project are notionally administered as parts of Sansha in Hainan Province. As of December 2016, the projects in the Spratlys covered 3,200 acres (1,300 ha) of land protected by "'significant' weapons systems, including anti-aircraft and anti-missile systems".
