To the topic of ‘Wolf Warriors’, the policy dropped as early as May 2021 so it's highly possible that the change itself is not economic related (https://thediplomat.com/2022/01/is-china-putting-wolf-warrio...). The targeted audience (of the foreign policy) may not be the West, but global south. There is a paper (I'm too lazy to find the link) claim that the ‘Wolf Warriors’ rhetoric used by China's diplomats in non-west country doesn't change much.
If you are intrested in the changes under Xi, Kevin Rudd has a series of deep analysis: https://viet-studies.net/kinhte/WorldAccordingtoXi_FA.pdf. Generally China's decision making process doesn't care too much about winning or competing or any particular goal especially in short term. They are based on long-term analisys of "what will happen inevitably" and back track from that conclusion. Many of these decisions make no sense from West's perspective under a cost-benefit analysis.
