From Palawan News (Jun 21, 2024): Chronology: The ongoing maritime dispute between the Philippines and China (By PN Conversations Research Team)
The South China Sea is the setting for an ongoing geopolitical conflict between the Philippines and China, which revolves around their conflicting territorial claims and strategic objectives.
This feature explores the intricate chronology of events, diplomatic strategies, and regional consequences that are influencing one of Asia’s most difficult conflicts.
Setting the Stage
Since the mid-20th century, the Philippines and China have asserted conflicting ownership of important maritime features in the West Philippine Sea, including Scarborough Shoal and Ayungin Shoal. China’s claim is mostly based on the contentious nine-dash line, which it claims is its historical boundary covering a substantial portion of the South China Sea. On the other hand, the Philippines asserts its rights in accordance with the United Nations Convention on the Law of the Sea (UNCLOS), contesting China’s extensive territorial aspirations.
1947 (China Marks South China Sea Claims)
China, under the nationalist Kuomintang party, demarcates its territorial claims in the South China Sea with an eleven-dash line, covering most of the area including the Pratas Islands, the Macclesfield Bank, and the Paracel and Spratly Islands. In 1949, the People’s Republic of China (PRC) was declared, and in 1953, the dashes were reduced to nine. China continues to use the nine-dash line to justify its territorial claims.

Landmark Legal Battles

The PCA’s ruling in July 2016, which invalidated China’s expansive nine-dash line claim and affirmed the Philippines’ rights under UNCLOS, marked a significant legal victory for Manila.
