Huawei boasted “impressive” chip technology until everyone found out it was not. The CCP bots boasted that Apple won’t be able to assemble phones in India as some sort of superior tech was needed, until Apple not only moved critical tech to India but now has a solid R&D here too. China seems to boast of a lot of “impressive” technology that no one uses as an end product or is easily supplanted by others. Even NDB magnets is something others can replicate - it is nothing path breaking. Germany and India are now working to commercialize a magnet free EV transmission. Mahindra EVs are highly admired in Australia for their design and performance.
Planting paid stories in news media around the world won’t get you sales or adoption of your products, especially when the world sees the cutting corners practices of Chinese companies (as we saw in the building collapse in Thailand and the numerous failed strictures currently from flooding). Transparency and ethical business practices will.
Meanwhile commercially viable robotaxis, supersonic passenger flights, space travel, next age weapons, medical devices, medicines etc all still come from the West.
Right now, China is harping on EVs like it did with semi conductors once boasting world beating tech until almost all semiconductor companies went bankrupt in China. We see piles of EVs parked across China with no buyers. Many are catching fire and destroying nearby buildings and vehicles due to poor battery manufacturing processes. Simply boasting will not get you any sales just like your military equipment was found worthless by many countries.
