How to resolve the South China Sea issue

How to resolve the South China Sea issue: "The South China Sea issue is complicated with legal disputes, which should be solved within the framework of international laws, including the Charter of United Nations, the 1982 UN Convention on the Law of the Sea (UNCLOS) and the 2002 Declaration on the Conduct of Parties in the South China Sea.
The legal disputes can be divided into two parts: China's territorial disputes with some Southeast Asian countries, and its disagreements with the US on military action in the region. The US claims to defend free navigation in the South China Sea, but actually it is defending its own military interests."
