National pride, military ambition, historic and symbolic attachments and trillions of dollars-worth of trade have led to a fierce territorial dispute currently being fought among seven claimants—Brunei, China, Malaysia, the Philippines, Taiwan, Vietnam and Indonesia—over the South China Sea. The rich and bountiful oil reserves hidden in those waters has added another layer to the dispute(s). At various points during the past half-century, the disputes have led to skirmishes and legal issues between the claimants. The China-US battle for supremacy in the international order has only raised the stakes in the region. And it appears likely, that the dispute, based on recent developments—including the construction and militarization of islands—will continue to generate further controversies for the foreseeable future.
