The Tribunal also ruled Chinese activity in the region was illegal, found China to be violating its obligations under UNCLOS and failing to protect the natural habitats (including willful destruction of the coral and endangered species). China's harassment of Philippine ships was also ruled illegal. The nine-dash line was ruled invalid. China's claims of "historic waters" was found to be groundless. Mischief Reef, Second Thomas Shoal, and Reed Bank were found to “form part of the exclusive economic zone and continental shelf of the Philippines.”
Really, this was about as complete a victory for the Philippines (and refutation of everything China claims and is doing) as possible.
