A Soviet-style flag. Nozomi Kariyasu, 16 September 2009
While the shape of hammer and sickle does seem to vary somewhat, it seems that the official design, or at least the one which is in widespread use, is indeed the one currently shown here.
"A Soviet style flag" description is not quite correct, since the Soviet flag has had the hammer and sickle in the canton, while this one has them in the center, just like many other Asian Communist flags, for example the Communist Party of the Philippines and many Communist parties from India, so it might be more precise to describe it as an "Asian style Communist flag."
