Why accusations of Chinese NEV industry "overcapacity" are groundless

Some US and Western politicians and media outlets have recently claimed "overcapacity" in China's industrial sector.

Why does the "overcapacity" narrative conflict with the global demand for new energy vehicles and basic economic principles?
