Taiwan’s Ministry of Economic Affairs has significantly expanded its strategic export restrictions, officially listing Chinese technology heavyweights Huawei and Semiconductor Manufacturing International Corporation (SMIC) as controlled customers. This move, announced on June 10, arises from national security deliberations that focused on impeding the spread of sensitive technology and preventing circumvention of global arms controls. Effective immediately, Taiwanese companies are prohibited from exporting semiconductors, lithography machines, and related advanced equipment to Huawei or SMIC without explicit government authorization. Taiwan Semiconductor Manufacturing Company (TSMC), the world’s top contract chipmaker, was quick to affirm its full compliance. TSMC clarified that it has not fulfilled any orders for Huawei since September 2020 and is stepping up inspection and approval mechanisms to block all unsanctioned transactions. These stricter regulatory procedures follow an earlier incident where TSMC faced a billion-dollar US fine after investigators discovered unauthorized shipments—specifically, two million advanced Artificial Intelligence chiplets—for Huawei’s Ascend 910B accelerator platform via indirect channels.
This latest move further isolates Huawei and SMIC, adding to the considerable obstacles they already face under stringent US export controls. The United States has previously barred both entities from receiving critical US-origin technologies, design tools, and components required for next-generation chip development. Such restrictions have forced the Chinese companies to intensify efforts toward domestic innovation and semiconductor self-reliance. However, experts note that replicating the sophisticated processes needed for reliable extreme ultraviolet lithography—essential for leading-edge chip manufacture—will take years of focused investment and technical trial-and-error. Decoupling from foreign expertise is expected to create inefficiencies and slowdowns across the Chinese semiconductor sector.
In response, China has mobilized state-backed research institutes and industry partners in a national push to build indigenous alternatives. Recent reports indicate that China’s inaugural homegrown EUV lithography systems are expected to begin trial production by the third quarter of 2025, while parallel projects aim to develop domestic advanced chip packaging tools capable of challenging incumbent leaders like ASML. Even so, industry analysts caution that these ambitious initiatives will require sustained funding, specialized talent, and patience; parity with global semiconductor leaders is still a distant aspiration. The intersection of export controls, geopolitics, and technology competition continues to shape the evolving dynamics of the global semiconductor supply chain.
