"Great Wall of Sand" is a name first used in March 2015 by US Admiral Harry Harris, who was commander of the Pacific Fleet, to describe a series of uniquely very large-scale land reclamation projects by the People's Republic of China (PRC) in the Spratly Islands area of the South China Sea in the period from late 2013 to late 2016. [1]
In late 2013, the PRC embarked on very large scale reclamations at seven locations — in order to strengthen territorial claims to the region demarcated by the "nine-dash line". [2] [3] [4]
The artificial islands were created by dredging sand onto reefs which were then concreted to make permanent structures. By the time of the 2015 Shangri-La Dialogue, over 810 hectares (2,000 acres) of new land had been created. [5] By December 2016 it had reached 1,300 hectares (3,200 acres) and "'significant' weapons systems, including anti-aircraft and anti-missile systems" had been installed. [6]
The PRC states that the construction is for "improving the working and living conditions of people stationed on these islands", [7] and that, "China is aiming to provide shelter, aid in navigation, weather forecasts and fishery assistance to ships of various countries passing through the sea." [8]
Defence analysts IHS Jane's states that it is a "methodical, well planned campaign to create a chain of air and sea-capable fortresses". [9] These "military-ready" installations include sea-walls and deep-water ports, barracks and notably include runways on three of the reclaimed "islands", including Fiery Cross Reef, [10] [11] Mischief Reef and Subi Reef. [2] Aside from geo-political tensions, concerns have been raised about the environmental impact on fragile reef ecosystems through the destruction of habitat, pollution and interruption of migration routes. [12]
The Asia Maritime Transparency Initiative's "Island tracker" has listed the following locations as the sites of the PRC island reclamation activities: [13]

Total reclaimed area by PRC on 7 reefs: approx. 13.5 square kilometres (5.2 sq mi)
The PRC used hundreds of dredges and barges including a giant self-propelled dredger, the Tian Jing Hao. [14] [15] Built in 2009 in China, the Tian Jing Hao is a 127 m (417 ft) long seagoing cutter suction dredger designed by German engineering company Vosta LMG; (Lübecker Maschinenbau Gesellschaft (de)). At 6,017 gross tons, with a dredging capacity of 4500 m3/h, it is credited as being the largest of its type in Asia. It has been operating on Cuarteron Reef, the Gaven Reefs, and at Fiery Cross Reef. [16]
More than half of the world's annual merchant fleet tonnage passes through the Strait of Malacca, Sunda Strait, and Lombok Strait, with the majority continuing on into the South China Sea. Tanker traffic through the Strait of Malacca leading into the South China Sea is more than three times greater than Suez Canal traffic, and well over five times more than the Panama Canal. [17] The People's Republic of China (PRC) has stated its unilateral claim to almost the entire body of water. [18]
As the Mischief and Subi Reefs were under water prior to reclamations, they are considered by the Third United Nations Conference on the Law of the Sea (UNCLOS III) as "sea bed" in "international waters". Although the PRC had ratified a limited [19] UNCLOS III not allowing innocent passage of war ships, according to the UNCLOS III, features built on the sea bed cannot have territorial waters. [19]
The PRC has ratified UNCLOS III; [19] the convention establishes general obligations for safeguarding the marine environment and protecting freedom of scientific research on the high seas, and also creates an innovative legal regime for controlling mineral resource exploitation in deep seabed areas beyond national jurisdiction, through an International Seabed Authority and the common heritage of mankind principle. [20]
According to Chinese sources, the concept was invented in 1972 by the Bureau of Survey and Cartography of Vietnam under the Office of Premier Phạm Văn Đồng which printed out "The World Atlas" and said, "The chain of islands from the Nansha and Xisha Islands to Hainan Island, Taiwan Island, the Penghu Islands and the Zhoushan Islands are shaped like a bow and constitute a Great Wall defending the China mainland." [21]
Aside from geo-political tensions, concerns have been raised about the environmental impact on fragile reef ecosystems through the destruction of habitat, pollution and interruption of migration routes. [12] These new islands are built on reefs previously one metre (3 ft) below the level of the sea. For back-filling these seven artificial islands, a total area of 13.5 square kilometres (5.2 sq mi), to the height of few meters, China had to destroy surrounding reefs and pump 40 to 50 million m3 (1.4 to 1.8 billion cu ft) of sand and corals, resulting in significant and irreversible damage to the environment. Frank Muller-Karger, professor of biological oceanography at the University of South Florida, said sediment "can wash back into the sea, forming plumes that can smother marine life and could be laced with heavy metals, oil and other chemicals from the ships and shore facilities being built." Such plumes threaten the biologically diverse reefs throughout the Spratlys, which Dr. Muller-Karger said may have trouble surviving in sediment-laden water. [36]
Rupert Wingfield-Hayes, visiting the vicinity of the Philippine-controlled island of Pagasa by plane and boat, said he saw Chinese fishermen poaching and destroying the reefs on a massive scale. As he saw Chinese fishermen poaching endangered species like massive giant clams, he noted "None of this proves China is protecting the poachers. But nor does Beijing appear to be doing anything to stop them. The poachers we saw showed absolutely no sign of fear when they saw our cameras filming them". He concludes: "However shocking the reef plundering I witnessed, it is as nothing compared to the environmental destruction wrought by China's massive island building programme nearby. The latest island China has just completed at Mischief Reef is more than 9km (six miles) long. That is 9km of living reef that is now buried under millions of tonnes of sand and gravel." [37]
A 2014 United Nations Environment Programme (UNEP) report noted that "Sand is rarer than one thinks." [38] "The average price of sand imported by Singapore was US$3 per tonne from 1995 to 2001, but the price increased to US$190 per tonne from 2003 to 2005". [38] Although the Philippines and the PRC had both ratified the UNCLOS III, [19] in the case of Johnson South Reef, Hughes Reef and Mischief Reef, the PRC dredged sand for free in the EEZ the Philippines had claimed from 1978, [39] arguing this to be the "waters of China's Nansha Islands". "Although the consequences of substrate mining are hidden, they are tremendous. Aggregate particles that are too fine to be used are rejected by dredging boats, releasing vast dust plumes and changing water turbidity". [38]
John McManus, a professor of marine biology and ecology at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science, said: "The worst thing anyone can do to a coral reef is to bury it under tons of sand and gravel ... There are global security concerns associated with the damage. It is likely broad enough to reduce fish stocks in the world's most fish-dependent region." He explained that the reason "the world has heard little about the damage inflicted by the People's Republic of China to the reefs is that the experts can't get to them", and noted "I have colleagues from the Philippines, Taiwan, PRC, Vietnam and Malaysia who have worked in the Spratly area. Most would not be able to get near the artificial islands except possibly some from PRC, and those would not be able to release their findings". [40]
The Paracel Islands, also known as the Xisha Islands and the Hoàng Sa Archipelago, are a disputed archipelago in the South China Sea.
The Spratly Islands are a disputed archipelago in the South China Sea. Composed of islands, islets, cays, and more than 100 reefs, sometimes grouped in submerged old atolls, the archipelago lies off the coasts of the Philippines, Malaysia, and southern Vietnam. Named after the 19th-century British whaling captain Richard Spratly who sighted Spratly Island in 1843, the islands contain less than 2 km2 of naturally occurring land area, which is spread over an area of more than 425,000 km2 (164,000 sq mi).
The South China Sea is a marginal sea of the Western Pacific Ocean. It is bounded in the north by South China, in the west by the Indochinese Peninsula, in the east by the islands of Taiwan and northwestern Philippines, and in the south by the Indonesian islands of Borneo, eastern Sumatra and the Bangka Belitung Islands, encompassing an area of around 3,500,000 km2 (1,400,000 sq mi). It communicates with the East China Sea via the Taiwan Strait, the Philippine Sea via the Luzon Strait, the Sulu Sea via the straits around Palawan, and the Java Sea via the Karimata and Bangka Straits. The Gulf of Thailand and the Gulf of Tonkin are part of the South China Sea.
An artificial island is an island that has been constructed by humans rather than formed through natural processes. Other definitions may suggest that artificial islands are lands with the characteristics of human intervention in their format process, while others argue that artificial islands are created by expanding existing islets, constructing on existing reefs, or amalgamating several islets together. Although constructing artificial islands is not a modern phenomenon, there is no definite legal definition of it. Artificial islands may vary in size from small islets reclaimed solely to support a single pillar of a building or structure to those that support entire communities and cities. Archaeologists argue that such islands were created as far back as the Neolithic era. Early artificial islands included floating structures in still waters or wooden or megalithic structures erected in shallow waters.
Taiping Island, also known as Itu Aba, and various other names, is the largest of the naturally occurring Spratly Islands in the South China Sea. The island is elliptical in shape being 1.4 kilometres (0.87 mi) in length and 0.4 kilometres (0.25 mi) in width, with an area of 46 hectares. It is located on the northern edge of the Tizard Bank. The runway of the Taiping Island Airport is easily the most prominent feature on the island, running its entire length.
Scarborough Shoal, also known as Bajo de Masinloc, Huangyan Island, Minzhu Jiao and Panatag Shoal, are two skerries (rocks) located between Macclesfield Bank to the west and Luzon to the east. Luzon is 220 kilometres (119 nmi) away and the nearest landmass. The atoll is a disputed territory claimed by the Republic of the Philippines through the 1734 Velarde map, while the People's Republic of China and the Republic of China (Taiwan) claim it through the disputed nine-dash line. The atoll's status is often discussed in conjunction with other territorial disputes in the South China Sea such as those involving the Spratly Islands, and the 2012 Scarborough Shoal standoff. It was administered by the Philippines as part of its Zambales province, until 2012, when a standoff was initiated by China through the use of warships against fishing boats, resulting in effective capture by the Chinese maritime forces.
Spratly Island,, also known as Storm Island, is the fourth largest of the naturally occurring Spratly Islands in the South China Sea with an area of 15 hectares, and the largest of the Vietnamese-administered Spratly islands.
Sand Cay10°22′30″N114°28′48″E, also known as Bailan Island ; Son Ca Island ; Mandarin Chinese: 敦謙沙洲/敦谦沙洲; pinyin: Dūnqiān Shāzhōu, is a cay on the north edge of the Tizard Bank of the Spratly Islands in the South China Sea. With an area of 7 hectares, it is the ninth largest, and the fourth largest former Vietnamese-administered, of the Spratly Islands. The island has been occupied by Vietnam since 1974,. It is also claimed by China (PRC), the Philippines, Vietnam, and Taiwan (ROC).
Johnson South Reef, also known in Mandarin Chinese: 赤瓜礁; pinyin: Chìguā Jiāo; Mabini Reef ; Vietnamese: Đá Gạc Ma), is a reef in the southwest portion of the Union Banks in the Spratly Islands of the South China Sea. It is controlled by the People's Republic of China (PRC), but its ownership is disputed and also claimed by the Philippines, Taiwan (ROC), and Vietnam.
Subi Reef, also known as Zamora Reef ; Zhubi Reef ; Vietnamese: đá Xu Bi, is an atoll in the Spratly Islands of the South China Sea located 26 km (16 mi) southwest of Philippines' Pag-asa island Thitu Island under the municipality of the Kalayaan Island Group, Palawan province as claimed by Philippines. It is occupied by China (PRC), and claimed by Taiwan (ROC) and Vietnam. According to the claims of the PRC, it currently falls under the de facto jurisdiction of Nansha islands, Sansha city, Hainan province, China. But under the clauses of the UNCLOS, which the PRC is also a signatory, the international law only the Philippines has the maritime rights to exploit its resources or build structures, as it is within the continental shelf of the coastal country.
Mischief Reef, also known as Panganiban Reef, is a low tide elevation (LTE) reef/atoll surrounding a large lagoon in the SE of Dangerous Ground in the east of the Spratly Islands in the South China Sea. It is located 250 kilometres (130 nmi) west of Palawan Island of the Philippines. Administratively, it belonged to the Kalayaan Islands municipality of the province of Palawan. It is also under the de facto jurisdiction of Nansha islands, Sansha City, Hainan province, China. Activities by the People's Republic of China (PRC) in the mid-2010s have created a large artificial island on the atoll including an approximately 2,700-metre (8,900 ft) runway and associated airfield.
The Spratly Islands dispute is an ongoing territorial dispute between Brunei, China, Malaysia, the Philippines, Taiwan, and Vietnam concerning "ownership" of the Spratly Islands, a group of islands and associated "maritime features" located in the South China Sea. The dispute is characterized by diplomatic stalemate and the employment of military pressure techniques in the advancement of national territorial claims. All except Brunei occupy some of the maritime features.
The nine-dash line, also referred to as the eleven-dash line by Taiwan, is a set of line segments on various maps that accompanied the claims of the People's Republic of China and the Republic of China in the South China Sea. The contested area includes the Paracel Islands, the Spratly Islands, the Pratas Island and the Vereker Banks, the Macclesfield Bank, and the Scarborough Shoal. Certain places have undergone land reclamation by the PRC, ROC, and Vietnam. The People's Daily of the PRC uses the term Duànxùxiàn (断续线) or Nánhǎi Duànxùxiàn, while the ROC government uses the term Shíyīduàn xiàn.
Territorial disputes in the South China Sea involve conflicting island and maritime claims in the South China Sea by several sovereign states, namely the People's Republic of China (PRC), Taiwan, Brunei, Malaysia, the Philippines, and Vietnam. The disputes involve the islands, reefs, banks, and other features of the region, including the Spratly Islands, Paracel Islands, Scarborough Shoal, and various boundaries in the Gulf of Tonkin. The waters near the Indonesian Natuna Islands, which some regard as geographically part of the South China Sea, are disputed as well. Maritime disputes also extend beyond the South China Sea, as in the case of the Senkaku Islands and the Socotra Rock, which lie in the East China Sea.
Fiery Cross Reef, also known as "Northwest Investigator Reef", Mandarin Chinese: 永暑礁; pinyin: Yǒngshǔ Jiāo; Kagitingan Reef ; Vietnamese: Đá Chữ Thập, is a militarized reef occupied and controlled by China (PRC) as part of Sansha of Hainan Province and is also claimed by the Republic of China (ROC/Taiwan), the Philippines and Vietnam.
The Gaven Reefs, also known in Mandarin Chinese: 南薰礁; pinyin: Nánxūn Jiāo and Chinese: 西南礁; pinyin: Xīnán Jiāo; Burgos Reefs ; Vietnamese: Đá Ga Ven and Vietnamese: Đá Lạc, is a group of two reefs in the Tizard Bank of the Spratly Islands in the South China Sea.
The South China Sea Arbitration was an arbitration case brought by the Republic of the Philippines against the People's Republic of China (PRC) under Annex VII of the United Nations Convention on the Law of the Sea concerning certain issues in the South China Sea, including the nine-dash line introduced by the mainland-based Republic of China since as early as 1947. A tribunal of arbitrators appointed the Permanent Court of Arbitration (PCA) as the registry for the proceedings.
The article covers events that are related to the South China Sea dispute. In the South China Sea, historically China, Japan and France have disputed over Spratly and Paracel Islands. Presently, the Paracel Islands are disputed among China (PRC), Taiwan (ROC), and Vietnam, while Pratas Island is contested between China and Taiwan. Additionally, the Spratly Islands are subject to intertwined claims by China, Taiwan, Vietnam, the Philippines, Malaysia, and Brunei. Because of this, numerous countries with territorial disputes have had conflicts in the South China Sea since the past.
Vietnam claims an exclusive economic zone (EEZ) of 1,395,096 km2 (538,650 sq mi) with 200 nautical miles from its shores.
