(VOVWORLD) - China has recently included the image of the controversial nine-dash line on T-shirts, lapel pins, globes, maps, digital maps, and in films and textbooks. This shows that China does not miss any opportunity to promote its baseless claims to the East Sea. The so-called nine-dash line was rejected by the Permanent Court of Arbitration in 2016. Vietnam, other regional countries, and the international community should work closely with each other to fight Beijing’s false claims. In this week’s Q&A, we discuss the issue with Carl Thayer, Emeritus Professor at the University of New South Wales, Australian Defence Force Academy.
