Vietnam is Censoring Politically Sensitive Maps. It's Not Finished and Not Alone Ralph Jennings TAIPEI - The dramatic demise in Vietnam of two maps that show China's claim to a disputed tract of sea herald a longer-term effort at expunging material that officials find politically offensive -- and not just in Vietnam. Both maps, one in a luxury Volkswagen car and the other in a DreamWorks film, show the nine-dash line that Beijing uses to demarcate its claims in the South China Sea. Vietnamese officials contest the line and say some of the waters within it are theirs. The two countries have sparred since the 1970s over maritime sovereignty. Vietnam will probably keep censoring material that implies Chinese sovereignty over the 3.5 million-square-kilometer sea, Asia scholars say. They would effectively follow China's continued use of authoritarian rule to ban websites and publications that violate its stances on international issues. "I think this is but the latest series of essentially what I would call posturing," said Oh Ei Sun, senior fellow with the Singapore Institute of International Affairs. "You have to keep on emphasizing your sovereignty over a certain part, because if you don't, then the international community will think that you are giving up." .
