The Sino-Philippine conflict over territory in the South China Sea has been ongoing for years. China claims sovereignty over almost the entire South China Sea based on what it calls its "nine-dash line," which includes territory also claimed by the Philippines, Vietnam, Malaysia, Taiwan and Brunei. The Philippines has brought its claims to an international arbitration case and received a ruling in its favor, but China has rejected this ruling. Resolving this complex territorial dispute will require diplomatic negotiations between the involved parties.
