WASHINGTON, Nov 15 — Chinese companies are buying up US chipmaking equipment to make advanced semiconductors, despite a raft of new export curbs aimed at thwarting advances in the country’s semiconductor industry, a report said yesterday.

The 741 page annual report, released by the US-China Economic and Security Review Commission, takes aim at the Biden administration’s October 2022 export curbs, which seek to bar Chinese chipmakers from getting US chipmaking tools if they would be used to manufacture advanced chips at the 14 nanometre node or below.

With the Commerce Department using the 14 nanometre restriction limit, "importers are often able to purchase the equipment if they claim it is being used on an older production line, and with limited capacity for end-use inspections, it is difficult to verify the equipment is not being used to produce more advanced chips,” the report stated.

The finding comes as the United States scrambles to figure out how Chinese telecoms giant Huawei was able to produce an advanced 7 nanometre chip to power its Mate 60 Pro smartphone at China’s top chipmaker SMIC, despite the export curbs announced last year.

Huawei and SMIC were also added to a trade restriction list in 2019 and 2020, which in theory bars US suppliers from shipping certain technology to the companies.

China watchers had theorized that SMIC could have made the chip with equipment obtained prior to the October 2022 rules, but it had other options for obtaining the equipment from oversees, the report shows.

The United States managed to plug a key loophole in its efforts to stymie China’s access to advanced chipmaking tools by convincing allies Japan and the Netherlands, with similarly robust chipmaking equipment industries, to announce their own restrictions on exports of the coveted technology.

But China stockpiled equipment by taking advantage of the lagtime between the United States’ October 2022 rules, and Japan and the Netherlands’ similar moves in July and September of 2023 respectively, the report details.

According to the document, between January and August 2023, China imported US$3.2 billion (RM14.9 billion) worth of semiconductor manufacturing machines from the Netherlands, a 96.1 per cent increase over the US$1.7 billion recorded over the same period in 2022. China’s imports of semiconductor equipment from all countries totalled US$13.8 billion over the first eight months of 2023, it added.

The report does not outline a specific recommendation to address the gaps in the US rules, but urges Congress to request an annual evaluation, to be completed within 6 months by the General Accountability Office and later made public, of the effectiveness of export controls on chipmaking equipment to China.

The US-China Economic and Security Review Commission was created in 2000 to submit an annual report to Congress on the national security implications of the economic ties between the United States and China, and to provide recommendations for government action. — Reuters
