Could be, but China's imports from the US where not much (6% of their total) and cannot be easily substituted from SEA countries, as they were mostly importing a ton of agricultural stuff (soybeans, corn) plus fossils.

I understand 6% of china may be a much higher percentage of, say, Vietnam's export, but I just don't think Vietnam can produce that much more of that, quickly.
