I wouldn't get too hung up on these labels when it comes to China, they dont practice Communism there, its more like a lifestyle brand to neuter the class discussions entirely in China as nothing in modern China is remotely communist. Arguably China is perhaps the most fascist country in the world today given the whole ethnic Han supremacist worldview going on, not to mention the obsession with genetics and CRISPR technology, etc. It's very complicated to understand internal power dynamics of China as an outsider, and who maps to whom, but there are generally 3 main power factions: the Princeling faction (Xi Jinping), the Shanghai Clique (formerly Deng Xiaoping's faction), and the Communist Youth League faction (Hu Jintao and Li Keqiang's faction). A way to understand it is Xi Jinping is more like the MAGA/Trump faction of America, Shanghai Clique was more akin to Bush-Era Republicans, and the Communist Youth League were more like the Clinton/Obama technocratic centrists.
You could imagine a situation where Usha's involvement in China isn't about her being communist, but more linking with Xi Jinping's power network, which at the time she was there would have been the weakest of the three factions. I don't think it's an accident all these nationalists emerged when they did across multiple countries, there is clearly a global cooperative network going on here, especially when you consider that Shinzo Abe and Xi Jinping both took charge about 4 weeks apart, in the same year (2012) which Putin took charge in Russia. Modi then took charge about 18 months later. Just saying, its not an accident all these things happened when they happened, there was obviously a very coordinated, rather shadowy effort to bring these four populist nationalists to power within a 2 year window, which clearly had the ripple effect on accelerating Trump's rise soon after.
