The Pentagon officially added Alibaba, Baidu, BYD, and a broad range of other Chinese companies to its list of firms it considers linked to China's military. The list, formally called the Section 1260H list, has been updated annually since 2021 and now covers well-known consumer brands alongside defense and chip companies.
The designations do not freeze assets or stop trade. What they do is create a legal barrier between these companies and US government money. Starting June 30, 2026, the Defense Department cannot sign contracts directly with any company on the list. From June 2027, it cannot buy their products or services even through middlemen. Any US company that both supplies the Pentagon and sources from a listed firm will need to make a choice.
For companies like Alibaba and Baidu, whose US presence includes cloud services, research partnerships, and advertising, the designation creates a compliance problem for every American counterpart that does business with them. For physical product makers like BYD, already facing 100 percent tariffs on vehicles entering the US, the label adds a further layer of friction on top of an already restricted market.
The political backstory here is important. The Pentagon first posted this updated list in February, then pulled it before Trump's May trip to Beijing to meet Xi Jinping. The meeting was closely watched for signs of easing tensions, but yielded little on technology. Re-posting the list, now expanded, is a public signal that whatever was discussed in Beijing did not slow this process down.
With this update, all three of China's largest AI companies, Alibaba, Baidu, and Tencent, which was added in 2025, are now on the list. One analyst at the Foundation for Defense of Democracies put it plainly: "Washington is no longer treating these as isolated companies. It is treating the entire technology stack as strategically contested."
The pressure is spreading beyond the US. Taiwan is now considering its own export controls that would restrict AI chip sales to all Chinese buyers, not just the companies already on blacklists like Huawei. That would close a significant gap: advanced chips made in Taiwan have been reaching Chinese companies through intermediaries, and a broader Taiwanese restriction would make that considerably harder.
For businesses outside the defense sector, none of this triggers an immediate legal obligation. But the trajectory is consistent and has been for several years: the list of Chinese technology firms that Western companies can work with cleanly is shrinking. Firms that use Chinese cloud services, source components from Chinese tech manufacturers, or have research partnerships with listed companies should take note of where the contracting deadlines fall.
Some companies have fought back successfully. Xiaomi won a court challenge and was removed from the list in 2021. Tencent is still contesting its 2025 inclusion. The listed firms can petition for removal, and several have announced they will. But the list is also growing each year, not shrinking.
