The South China Sea
The South China Sea is a crucial maritime region, notable for its extensive area of approximately 3.5 million square kilometers and its significant geopolitical relevance. This sea, bordered by several countries including China, Vietnam, the Philippines, and Malaysia, is a vital conduit for global trade. It is estimated that over one-third of the world’s shipping traffic navigates through these waters, underscoring its importance in international commerce. The South China Sea is also home to some of the most active shipping routes, linking the Pacific and Indian Oceans.
In addition to its strategic shipping lanes, the South China Sea is rich in natural resources. Reports suggest that the region contains substantial oil and natural gas reserves, enticing various nations to assert claims to these resources. Moreover, the area supports an abundant biodiversity, including fishing grounds crucial to the livelihoods of millions in surrounding nations. The fisheries in the South China Sea are among the most productive globally, highlighting another layer of competition and dispute among neighboring countries.
However, the wealth of the region does not come without challenges. The South China Sea is characterized by a complex web of territorial disputes, primarily involving the Nine-Dash Line, a demarcation that China uses to assert its claims over vast areas of the sea. This line has led to heightened tensions with other countries that also claim rights to parts of the sea, resulting in a situation fraught with geopolitical implications.
China’s nine-dash line is a U-shaped demarcation on Chinese maps encompassing most of the South China Sea. Its legal basis is disputed, but it overlaps with the exclusive economic zones (EEZs) of several countries, including Brunei, Indonesia, Malaysia, the Philippines, Taiwan, and Vietnam. This overlap has created significant tension in the region, raising concerns about territorial rights, resource exploitation, and freedom of navigation. Image source: NamVietNews
China’s Nine-Dash Line
The South China Sea is a highly contested maritime region, central to geopolitical rivalry, particularly involving China and several Southeast Asian nations. At the heart of this conflict lies the Nine-Dash Line, a demarcation that traces China’s extensive claims over approximately 90% of the South China Sea. The origins of the Nine-Dash Line can be traced back to the early 20th century, specifically a map published by the Chinese government in 1947. This map introduced the dash line concept, which became a cornerstone of China’s maritime territorial assertions.
The Nine-Dash Line encompasses various islands, reefs, and maritime areas, which China asserts are part of its historical and sovereign rights. The significance of the line stretches beyond mere geography; it is a manifestation of China’s long-standing belief in its historical claim to these waters, based on ancient records and navigational practices. The line’s assertion has provided China with a historical pretext to pursue resource exploration visible in its activities involving oil and gas reserves, as well as aquatic resources within this expanse.
Legally, the Nine-Dash Line serves as a fundamental basis for China’s territorial claims in the South China Sea, despite opposition from neighboring countries such as Vietnam, the Philippines, and Malaysia. These nations contest China’s claims by referencing international law, particularly the United Nations Convention on the Law of the Sea (UNCLOS), which upholds the rights of coastal states to exclusive economic zones (EEZ) extending 200 nautical miles from their shorelines. China’s lack of recognition for UNCLOS as it relates to the Nine-Dash Line has resulted in growing tension, amplifying disputes and affecting regional stability.

Video narration: The Philippines on Sunday (August 25) accused Chinese vessels of blocking a ship transporting provisions to Filipino fishermen in the South China Sea, saying they had made “aggressive and dangerous” maneuvers, including ramming the ship and using water cannons. Handout footage from the Philippines’ South China Sea task force showed the Chinese coastguard ramming and using a water cannon at a fisheries vessel. China’s Coast Guard said it had taken “control measures” against the Philippine vessel that “illegally” entered into the waters near the Sabina shoal and had repeatedly dangerously approached its ships.
Incidents of Aggression by China
In recent years, China’s assertive actions in the South China Sea have raised significant concerns among neighboring countries and the international community at large. The South China Sea is a vital maritime area, rich in resources, and strategically important for global trade routes. However, China’s persistent intrusion into these waters has led to escalating tensions and a series of incidents that underscore its aggressive posture in the region.
One prominent example of China’s incursions is the establishment of artificial islands in the Spratly Islands. Beginning in the 2010s, China embarked on an extensive land reclamation project, transforming submerged reefs into military outposts. These islands, equipped with airstrips and military facilities, serve not only as strategic defense points but also as tools for asserting territorial claims over vast areas of the South China Sea. This move has been met with widespread international condemnation, as it violates principles of international law, specifically the United Nations Convention on the Law of the Sea (UNCLOS).
Moreover, the presence of the Chinese Coast Guard in contested waters has heightened tensions significantly. Incidents involving confrontations between Chinese vessels and those of neighboring countries, such as Vietnam and the Philippines, underscore the risks of escalation. For instance, Chinese fishing boats are frequently reported operating within the Exclusive Economic Zones (EEZs) of other nations, disregarding sovereignty claims and contributing to heightened maritime disputes. These aggressive maritime activities not only challenge the territorial integrity of Southeast Asian nations but also threaten regional stability and security.
The implications of China’s actions extend beyond its immediate neighbors. The commitment of the United States and other nations to uphold freedom of navigation through military operations has indicated a willingness to challenge China’s expansive claims. Such incidents form a complex backdrop against which regional dynamics are evolving, raising pressing questions about the future of international law and the framework for resolving disputes in the South China Sea.
Layang Layang Island (Swallow Reef), located within the disputed Spratly Islands, is a small island occupied and developed by Malaysia. Originally a tiny reef, Malaysia has significantly expanded the island through reclamation and construction, adding an airstrip and a Royal Malaysian Navy (RMN) base. This expansion has transformed Layang Layang into a strategic military outpost and a popular diving destination. Image source: Google Map
Claims by Malaysia And Other Countries
The South China Sea is a strategically significant maritime area, and several countries have made territorial claims that challenge China’s assertion over its Nine-Dash Line.
Malaysia
Malaysia asserts claims over several islands and maritime features within the Spratly Islands archipelago in the South China Sea. These claims encompass a range of features, including:
- Islands: Layang-Layang Island (Swallow Reef)
- Reefs: Erica Reef, Investigator Shoal, Mariveles Reef, Ardasier Reef, Commodore Reef, Amboyna Cay, Barque Canada Reef
- Shoals: James Shoal, North Luconia Shoals, South Luconia Shoals
Malaysia bases its claims on the United Nations Convention on the Law of the Sea (UNCLOS), specifically its rights to an Exclusive Economic Zone (EEZ) and continental shelf. These claims are integral to Malaysia’s efforts to safeguard its maritime boundaries and access to potential resources within its claimed EEZ.
However, Malaysia’s claims significantly overlap with those of several other nations, creating a complex and contentious situation in the region:
- China: China asserts its expansive “nine-dash line” claim, encompassing most of the South China Sea, including all the features claimed by Malaysia.
- Vietnam: Vietnam claims sovereignty over many of the same features as Malaysia, including Amboyna Cay and Barque Canada Reef.
- Philippines: The Philippines also claims some of the features claimed by Malaysia, including the Commodore Reef.
Philippines
Key features claimed by the Philippines include:
- Thitu Island (Pag-asa): The largest island occupied by the Philippines in the Spratlys, with a significant Philippine military presence.

- Lankiam Cay (Panata)
- Commodore Reef (Rizal): A significant reef with potential for resource exploration.
- Irving Reef (Balagtas): Another important reef with potential for resource exploration.
- Second Thomas Shoal (Ayungin): A strategically important shoal where a grounded Philippine warship remains, a constant point of contention with China.
These claims face significant overlap with those of other countries, primarily:
- China: China asserts its expansive “nine-dash line” claim, encompassing most of the South China Sea, including all the features claimed by the Philippines.
- Vietnam: Vietnam occupies several of the islands claimed by the Philippines.
- Taiwan: Taiwan also claims sovereignty over many of the same features.
- Malaysia: Malaysia claims sovereignty over some of the features claimed by the Philippines.
These overlapping claims create a complex and volatile situation in the South China Sea, with frequent incidents and standoffs between the claimant states. The Philippines has pursued various diplomatic and legal avenues to assert its claims, including through international arbitration.
Vietnam
Vietnam claims a substantial portion of the Spratly Islands, referred to as Truong Sa in Vietnamese, based on historical claims and its interpretation of the United Nations Convention on the Law of the Sea (UNCLOS).
Key islands and reefs claimed and occupied by Vietnam include:
- Amboyna Cay (An Bang Island)
- Bombay Castle (Ba Ke)
- Collins Reef (Co Lin Reef)
- Cornwallis South Reef (Nui Le Reef)
- Ladd Reef (Lat Reef)
- Namyit Island (Nam Yet Island)
- Sand Cay (Son Ca Island)
- Sin Cowe Island (Sinh Ton Island)
- Southwest Cay (Song Tu Tay Island)
- Spratly Island (Truong Sa Island)
Vietnam has significantly developed some of these islands, establishing military outposts, research stations, and even airstrips. This has strengthened its presence in the region and solidified its claims. However, Vietnam’s claims in the Spratly Islands face significant challenges due to overlapping claims from other countries:
- China: China asserts its expansive “nine-dash line” claim, encompassing most of the South China Sea, including all the features claimed by Vietnam.
- Taiwan: Taiwan also claims sovereignty over the entire Spratly Islands.
- Philippines: The Philippines claims several features within the Spratly Islands, some of which also overlap with Vietnam’s claims.
- Malaysia: Malaysia claims sovereignty over some features within the Spratly Islands, creating further overlapping claims with Vietnam.
These overlapping claims have led to numerous maritime incidents and heightened tensions in the South China Sea. Vietnam has consistently advocated for peaceful resolution of these disputes through diplomatic means and adherence to international law, particularly UNCLOS.
.
In response to China’s assertive actions in the South China Sea, including the rapid expansion of military bases and increased maritime intrusions, countries in the region have taken several key measures to enhance their defense capabilities. One key strategy has been the strengthening of regional security cooperation. This has manifested in the form of joint military exercises, such as the Rim of the Pacific (RIMPAC) exercise involving navies from numerous countries, including the United States and Malaysia (with the participation of KD Lekiu).
International Responses
The ongoing tensions in the South China Sea have elicited a range of responses from international actors, including the United States, ASEAN countries, and various global organizations. The complexity of the Nine-Dash Line claims has made the situation particularly contentious, aiming to balance national interests with regional stability.
One prominent response has been the military cooperation between the United States and its allies in the Asia-Pacific region. The U.S. has conducted various freedom of navigation operations (FONOPs) to challenge China’s expansive claims and assert its commitment to maintaining open sea lanes. This strategic military posturing serves as a warning against aggressive maneuvers by China while reinforcing alliances with nations such as Japan, Australia, and the Philippines.
ASEAN countries, for their part, have sought to grasp a unified stand on the South China Sea issue, though internal divisions often complicate collective action. The varying degrees of dependence on China for economic ties among member states can lead to conflicting interests, with some countries preferring diplomatic engagement over confrontational tactics.
Nevertheless, ASEAN has repeatedly called for adherence to international law, emphasizing the importance of the United Nations Convention on the Law of the Sea (UNCLOS) in resolving maritime disputes. Through initiatives like the ASEAN Regional Forum, member nations are working to enhance dialogue and foster understanding among the parties involved.
International organizations, such as the United Nations, play a crucial role in addressing maritime disputes. Their mechanisms provide forums for discussion and potential resolution of conflicts, although effectiveness can be limited due to sovereignty concerns and political nuances. The increasing influence of multilateral partnerships is also evident, with nations exploring collaborative agreements to ensure stability in the region. Overall, the international response to China’s assertiveness in the South China Sea demonstrates a delicate interplay between diplomatic negotiations, military alliances, and the overarching framework of international law.

The United Nations Convention on the Law of the Sea (UNCLOS) is an international agreement that establishes a comprehensive legal framework for all marine and maritime activities. It was adopted in 1982 and entered into force in 1994. China ratified UNCLOS in 1996 . However, China’s actions in the South China Sea, such as its extensive land reclamation projects and militarization of artificial islands, have been criticized by many countries as violating UNCLOS and undermining regional stability.
International Law and the UNCLOS
The South China Sea remains a focal point of geopolitical tensions, significantly shaped by international legal frameworks such as the United Nations Convention on the Law of the Sea (UNCLOS). Ratified in 1982, UNCLOS provides a comprehensive legal framework governing the rights and responsibilities of nations concerning ocean use, marine resources, and maritime boundaries. A critical aspect of UNCLOS is its delineation of territorial seas and exclusive economic zones (EEZs), which are vital for establishing sovereignty claims over maritime areas.
According to UNCLOS, coastal states are entitled to an EEZ extending 200 nautical miles from their baselines, within which they have exclusive rights to explore and exploit marine resources. However, the South China Sea is marked by overlapping claims among multiple nations, complicating the enforcement of these rights. China’s assertion of the nine-dash line, which it claims encompasses extensive waters and resources, raises significant challenges to UNCLOS’s provisions. Critics argue that this claim circumvents the rights granted to other states under international law, fostering tensions and disputes.
Moreover, while UNCLOS lays down legal pathways for dispute resolution, such as arbitration, its enforcement remains contentious. Notably, the Permanent Court of Arbitration ruled against China’s claims in July 2016, interpreting them as inconsistent with UNCLOS principles. Subsequently, China rejected the ruling, thereby undermining UN-based mechanisms aimed at conflict resolution. Additionally, the lack of a robust enforcement body under UNCLOS poses challenges for maintaining compliance among disputing nations.
Overall, understanding the South China Sea disputes necessitates a thorough examination of international law and UNCLOS’s role in mediating these complex territorial claims. Adherence to these legal frameworks is crucial for fostering stability and promoting a rules-based order in this strategically significant region.
In addition to its investments in modernizing its naval capabilities, Malaysia also benefits from significant external support. A prime example is the US$60 million security grant provided by the US Government. This substantial funding will be used to transform three existing CN235 cargo aircraft into cutting-edge maritime surveillance platforms. Equipped with advanced sensors and surveillance technology, these aircraft will provide crucial intelligence, enabling more effective maritime security operations. Image source: US Embassy, Malaysia
