That the Permanent Court of Arbitration, The Hague, Netherlands, has found that China has no historical title to the lion's share of the South China Sea and that China had pierced the sovereignty of the Philippines and that China had also damaged the ecosystem of reefs on the South China Sea, must then serve as notice of guilt of China's expansionist actions in Southeast Asia.
Yet, China has determined the ruling of an International Law court to be a "puppet" ruling from a body influenced by those whom it alleges wants to stir up trouble in the region. China also contends it has sovereignty over most of the sea.
However, in spite of Chinese non recognition of Tuesday's ruling, International Law has determined that China has no historical title over a large swath of the South China Sea and that China has breached the sovereignty of the Philippines while also damaging the delicate ecosystem of reefs in the sea.
Since the International Court has no enforcement powers, then it is the responsibility and the obligation of the strong member of west alliances in the region, upon the request from weaker numbers, to defend and to retake that particular nation's sovereignty from Chinese actions. In this manner then, International Law could be served and enforced on the South China Sea.
