I think whenever something like this happens, the first audience is always the people at home. These diplomats are speaking first and foremost to Beijing. I don't know what exactly it means that their performance will be well-received, but I'm going to assume that it will be. I think the same is probably true for the fervour you see in Chinese students abroad and in the "community" organizations Australia in particular seems to be seeing more of lately. These kinds of demonstration are one of the tangible ways in which China is and remains the center of the(ir) world.
