what is the basis of china in claiming spratly islands
Spratly Islands dispute The Spratly Islands are important for economic and strategic reasons. The Spratly area holds potentially significant, but largely unexplored, reserves of oil and natural gas, it is a productive area for world fishing, it is one of the busiest areas of commercial shipping traffic, and surrounding countries would get an extended continental shelf if their claims were recognised. In addition to economic incentives, the Spratlys sit astride major maritime trade routes to Northeast Asia, giving them added significance as positions from which to monitor maritime activity in the South China Sea and to potentially base and project military force from. In 2014, China drew increased international attention due to its dredging activities within the Spratlys, amidst speculation it is planning to further develop its military presence in the area.[2] In 2015 satellite imagery revealed that China was rapidly constructing an airfield on Fiery Cross Reef within the Spratlys whilst continuing its land reclamation activities at other sites.[3][4][5] Only China (PRC), Taiwan (ROC), and Vietnam have made claims based on historical sovereignty of the islands.[6] The Philippines, however, claims part of the area as its territory under UNCLOS, an agreement parts of which[7] have been ratified by the countries involved in the Spratly islands dispute.
