China uses the 9-dash line on its maps as an attempt to legitimize its claims over vast expanses of the resource-rich South China Sea, now considered to be one of the most volatile maritime areas in the world.



The film was a joint production between DreamWorks and China's Pearl Studio, which told the story of a Chinese teenager helping a yeti return to his home on Mount Everest.



Like Vietnam, the Philippines has claims in the South China Sea which China refused to recognize. This, despite a historic 2016 Hague ruling which asserted the Philippines’ rights in the West Philippine Sea and invalidated China’s 9-dash line. Other claimant states include Taiwan, Malaysia, and Brunei.
