Seven of the world’s largest semiconductor makers have set out plans to increase manufacturing and deepen tech partnerships in Japan as western allies step up efforts to reshape the global chip supply chain amid rising tensions with China.At an unprecedented meeting in Tokyo with Japanese prime minister Fumio Kishida, the heads of chipmakers including Taiwan Semiconductor Manufacturing, South Korea’s Samsung Electronics and Intel and Micron of the US described plans that could transform Japan’s prospects of re-emerging as a semiconductor powerhouse.

Micron said it expected to invest up to ￥500bn ($3.7bn), including Japanese state subsidies, to build a plant to produce cutting-edge extreme ultraviolet lithography technology in Hiroshima.

Samsung is also discussing setting up a ￥30bn research and development centre in Yokohama with pilot lines for semiconductor devices. Japanese government officials said the move followed a thaw in relations between Tokyo and Seoul. Samsung was not available for comment.
