Made in America, funded by China: The capital backdoor into US national security

The U.S. venture capital system has functioned for the past decade as an unregulated conduit for foreign state-linked capital to reach American companies holding sensitive Department of Defense, NASA, and federal agency contracts. The mechanism is neither novel nor technically illegal—it exploits the voluntary nature of limited-partner disclosure requirements in private fund structures, allowing adversarial foreign capital to flow into the U.S. national security infrastructure with zero regulatory visibility.

The issue crystallized in early 2025 when the Pentagon designated Tencent, the major Chinese technology conglomerate, as a Chinese military company. The subsequent Justice Department action—forcing Tencent to divest two board seats at Epic Games and surrender director appointment rights—captured media attention on consumer-facing assets like Fortnite. However, this enforcement action obscured the substantive problem: Tencent and similar state-linked entities maintain undisclosed limited-partner positions in American venture capital funds whose portfolio companies operate as contractors to the Department of War, NASA, and other federal agencies. These positions remain entirely invisible in public filings.

The structural vulnerability originates in two obscure but widely used financial instruments: Blocker LLCs and Alternative Investment Vehicles. Originally architected to shield foreign pension funds from U.S. tax obligations, these entities now serve a secondary—and more problematic—purpose. They render the identities of foreign limited partners invisible to the underlying portfolio companies receiving capital, to taxpayers whose research grants seeded the foundational technology, and to regulators responsible for national security protection. The result is asymmetric: a single Delaware LLC housed on a defense contractor's cap table can be capitalized entirely by Beijing-linked entities with no disclosure requirement binding any party.

The article emphasizes that this pattern is documented and operates bidirectionally across the venture ecosystem. The transparency deficit extends across the full spectrum of critical infrastructure investment, from deep-tech hardware to software platforms supporting federal operations. No regulatory filing requirement forces disclosure of these relationships, and the voluntary-disclosure framework has enabled a decade-long accumulation of foreign state capital in sensitive American technology companies without corresponding oversight mechanisms.
