TOKYO — U.S. President Donald Trump has imposed tariffs on nations around the world in the first months of his second term to revive American manufacturing, rattling Asian economies that rely heavily on exports for prosperity.
The unilateral U.S. moves — which include country-by-country blanket levies known as “reciprocal” tariffs, and duties on specific items such as steel and automobiles — are causing major disruptions to the global economy, where close links in supply chains have become the norm for doing business.
