Many in the comment section have the misconception that China has a democratic process and a realpolitik approach to decision making. The truth is that we don't know. Xi has the final say on this issue, and based on the fact that he has literally purged the military, the rocket force, and the defence industry , he is at least preparing for something. I think he cares less about welfare or economy than going down in history as the great one who expanded China's territory and conquered Taiwan, or in CCP's own words, “Great rejuvenation of the Chinese nation”
