Two Chinese nationals residing in California—Chuan Geng and Shiwei Yang, both aged twenty‑eight—have been arrested and charged by the US Department of Justice for allegedly exporting Nvidia’s advanced AI chips to China without the required licenses.

From October 2022 through July 2025, they reportedly used their company based in El Monte, ALX Solutions—established shortly after tightened export regulations—to ship high‑end Nvidia GPUs, including H100 and RTX 4090 models, through intermediary companies in Singapore and Malaysia.

These routes are commonly used to conceal illicit exports to China.

Payment records show they received funds directly from companies in Hong Kong and mainland China rather than the purported recipient firms between twenty twenty‑three and mid‑twenty twenty‑five .

ALX Solutions is said to have acquired over two hundred Nvidia H100 chips from a San Jose server firm, mislabeling destinations such as Singapore and Japan.

One invoice alone, valued at over twenty‑eight million dollars, was linked to a non‑existent recipient company in Singapore, according to court records.

The defendants are also accused of shipping Nvidia RTX 4090 graphics cards, all controlled under US export laws .

Chuan Geng, a lawful permanent resident, was released on a bond of two hundred fifty thousand dollars.

Shiwei Yang, who overstayed her visa, remains in custody pending a detention hearing scheduled for August twelfth.

Their formal arraignment is set for September eleventh.

Both face potential penalties under export control statutes .

The Department of Commerce’s Bureau of Industry and Security and the FBI continue to pursue investigations into the case as part of broader efforts to enforce export controls on advanced semiconductor technology .
