The US is 150% of China's GDP (in nominal numbers) [1]. AI claims that China's "purchasing power parity" GDP is $44t compared to $32t for the US. There is no way that the US, which has been the world's largest economy for decades, is 3% of China's GDP.

Exports to the US is about 20% of China's GDP [2].

Regardless of any of China's contingency plans, US exports are well above noise-levels.
