Hmm, really? To me it looks like a new pandemic every decade would crush the west and assure the dominance of Asian economies.
Just looking at how much better Asian countries have weathered the pandemic, it would seem that every pandemic would be a relative boon for Asia compared to the West.
China is looking to move away from export focused growth and has been developing a rich domestic market.
More broadly, the world has been stepping back a bit from China anyway, because its labor costs have risen significantly compared to other potential manufacturing centers.
