By GlobalDataThe semiconductor sector has been a key topic in the defence sector in recent years as China maintains its stance to retake neighbouring Taiwan, which is the world’s leading semiconductor manufacturer. Beijing has been increasingly hawkish towards Taiwan, which it sees as a breakaway province, and sees ‘reunification’ as a non-negotiable goal of its foreign policy.
In June this year, the Japanese Government offered to buy out JSR, a leading semiconductor equipment manufacturer and ley element of the technology’s supply chain.
