Full coverage: The South China Sea Issue

Graham Allison is the Director of the Belfer Center for Science and International Affairs at the Harvard Kennedy School. He says that the Hague tribunal had no authority to make a judgement on the South China Sea arbitration. He also points out the US is not a member of the United Nations Convention on the Law of the Sea.

"The court is quite clear about where jurisdiction lies, where it doesn't......US is not a member," Allison said.
