US sanctions Chinese research institutes as 2-year tech war escalates

The US Defense Department on July 23 added an unspecified number of Chinese research institutions to its "1286 list" of foreign entities engaged in problematic activities, the latest escalation in Washington's campaign to restrict China's access to sensitive technology. China's Ministry of Commerce responded six days later, on July 29, expressing "strong opposition and firm rejection" of the move, which it said overstretches the concept of national security.

"The US has politicized and weaponized economic and technological issues," a ministry spokesperson said in a statement, vowing to safeguard China's interests.

The 1286 list targets institutions engaged in research deemed to threaten US national security, distinct from the Commerce Department's Entity List but operating in parallel to restrict China's technology ecosystem. The expansion follows the Biden administration's December 2024 curbs that placed 140 Chinese companies on the Entity List and restricted high-bandwidth memory chip exports, and China's retaliatory ban on exports of gallium, germanium and antimony to the US the same month.

At stake is the trajectory of a technology cold war that has already cost the global semiconductor industry billions in lost revenue and forced supply chain restructuring. The last time Washington expanded sanctions on Chinese research entities in 2023, the Philadelphia Semiconductor Index fell 4.2% over the following two weeks while the yuan weakened 1.3% against the dollar. With the EU also tightening its own sanctions regime — including the 20th round of Russia-related sanctions that hit a historical high — Chinese technology companies face a multi-front compliance challenge that shows no sign of easing.

A widening sanctions architecture

The 1286 list operates alongside at least three other US sanctions mechanisms targeting Chinese technology: the Entity List, the Unverified List and the Federal Communications Commission's covered equipment list. Together they cover hundreds of Chinese entities across semiconductors, artificial intelligence, quantum computing and aerospace. The Commerce Department's December 2024 rules also expanded the "foreign direct product rule" to cover any item shipped to China containing US chips, regardless of where it was manufactured.

China's response has been calibrated but increasingly assertive. After the December 2024 US curbs, Beijing restricted exports of gallium, germanium, antimony, superhard materials and graphite — critical inputs for semiconductor manufacturing and defense applications where China holds dominant market share. China accounts for more than 80% of global gallium production and 60% of germanium, according to US Geological Survey data.

Market implications and the road ahead

For investors, the expanding sanctions regime creates persistent uncertainty across the technology supply chain. Chinese semiconductor equipment makers face restricted access to US components and software, while US companies with significant China exposure — including Applied Materials, which derived 40% of its $7.9 billion in China revenue in the nine months through July 2024 — confront shrinking addressable markets. The Philadelphia Semiconductor Index has declined 8.3% year-to-date as trade tensions have escalated.

The next flashpoint could come as soon as the EU's 21st sanctions round, currently under development, which may target additional Chinese entities. For Chinese research institutions now on the 1286 list, the immediate impact includes restricted access to US-origin technology and equipment, complicating research in advanced fields from artificial intelligence to biotechnology.
