Philippines Asserts Sovereignty Through Renaming of Kalayaan Island Group Features
The Philippine government is intensifying its efforts to solidify its territorial claims in the South China Sea by implementing a strategic renaming of maritime features. By assigning local names to 131 features within the Kalayaan Island Group (KIG), Manila aims to boost its sovereignty and formalize its presence in the region.
The Push for Local Nomenclature
President Ferdinand Marcos Jr. Has explicitly called for the use of Philippine names for features within the Kalayaan Island Group. This initiative is strongly supported by members of the House of Representatives, specifically the “House Young Guns,” who argue that the West Philippine Sea will always belong to the Philippines. The move is seen as a diplomatic and administrative tool to reinforce the country’s claim over these disputed territories.
Understanding the West Philippine Sea and the KIG
To understand the significance of this renaming, it is essential to define the geographic and legal framework the Philippines is using:

- West Philippine Sea (WPS): This is the official designation adopted by the Philippine government on September 5, 2012, via Administrative Order No. 29. It refers specifically to the parts of the South China Sea that fall within the country’s exclusive economic zone (EEZ).
- Kalayaan Island Group (KIG): Often designated in Philippine maps as the Spratly Islands, the KIG was established under Presidential Decree No. 1596 of 1978.
- Legal Basis: Philippine claims are supported by international treaty limits, including the 1898 Treaty of Paris and the 1900 Treaty of Washington, the latter of which retroactively included outlying territories.
Regional Tensions and China’s Response
The decision to rename these features has not been without controversy. China has issued warnings regarding the move, viewing the renaming as a provocative act. State-affiliated media, such as People’s Daily Online, have dismissed the strategy, suggesting that “playing the renaming game” only highlights Manila’s desperation in the ongoing maritime dispute.
Key Takeaways
- Scope: The Philippines is renaming 131 features within the Kalayaan Island Group.
- Objective: The primary goal is to boost national sovereignty and assert territorial rights.
- Official Standing: The West Philippine Sea designation was formalized in 2012, while the KIG was established by decree in 1978.
- International Friction: China has reacted with warnings, characterizing the move as a sign of desperation.
Looking Ahead
As the Philippines continues to formalize its nomenclature in the West Philippine Sea, the tension between Manila and Beijing is likely to persist. The use of local names serves as a symbolic and administrative marker of ownership, setting the stage for continued diplomatic and legal battles over the sovereignty of the Kalayaan Island Group and Scarborough Shoal.
