Background to conflict
- Conflict arose after WWII between China and three ASEAN nations (Indonesia, Malaysia and the Philppines) over the ownership of islands.
- The conflict became more intense during the 1990s after oil and gas reserves were tapped.
- The issue has now gone beyond territorial claims as the South Chin Sea has become the focal point for China-US rivalry. This has led to increased naval presence of both nations.
- China has responded to the US's instation of a naval presence by creating a naval base on the Spratly Islands. These islands are important economically as they hold oil and gas reserves.
- China is also artificially extending some islands by building larger bases out of imported sand to extend its territory, which is against UNCLOS law.
