If the goal is to just promote Chinese aesthetics, I think it's great. It positions China's traditional ceremonies and aesthetics as high value and class. In the race to keep modern industries growing, China has sometimes forgot to market it's culture to the same extent as say Japan has.I don’t think China wants to spread Confucianism, including proactively trying to convert anyone into believing Confucianism. The goal instead is to show the influences of Confucianism on the Chinese culture. If I am understanding it correctly, the Chinese government seems to be promoting Confucianism as being peaceful and tolerant to differences, according to the meaning of 中庸之道, therefore to convince others that this is how China thinks, talks and walks.
But I don't see any role for Confucianism as an ideology today. At least not in its original form. China should continue to dictate its relations with junior partners according to the Marxist model, which means guiding them from each stage of economic development (feudalism/elite family rule -> capitalism/market socialism -> communism) and at each stage establish mutually beneficial policies that help China and helps the partner.
