As Chinese warships rehearsed a blockade of Taiwan this month, they simulated a scenario that global leaders and policymakers have been busy worrying about: not war, but a grinding halt to the electronic supply chains that make the modern world run.

Taiwan’s biggest trading partners — which include China, the United States, Europe and Japan — have different ideas about the self-ruled island’s political future, yet all share common ground in one desire: to expand their piece of its cutting-edge semiconductor industry.

Beginning with U.S. House Speaker Nancy Pelosi’s visit early this month, a succession of American delegations have kissed the ring of top Taiwan chip executives. There’s much to gain. In recent years, Taiwan’s biggest chipmaker, Taiwan Semiconductor Manufacturing Company, or TSMC, has pledged to open new factories in the United States and Japan. The Taiwan chip design firm MediaTek recently partnered with Purdue University to open a chip design center.
