According to foreign media sources, the US government is investigating allegations that Chinese flash memory provider Yangtze River Storage provided chips to Huawei, and if true, Yangtze River Storage may be sanctioned for violating the US export ban against Huawei.

According to the report,The White House and the U.S. Department of Commerce received a "credible" report from Tech Insights, a professional disassembly analysis organization, showing that Yangtze River Storage provided a NAND Flash flash memory chip for Huawei's Enjoy 20e mobile phone, manufactured in August 2021.

At that time, former US President Trump had imposed an export ban on Huawei for a year, and the US government had also banned any US enterprise or foreign business from exporting any US technology or products containing US technology to Huawei.

According to sources, U.S. Customs is actively investigating allegations of violations of the Export Administration Regulations by Yangtze River Storage, but any enforcement action will have to wait until the investigation is completed.

Michael McCaul, chief member of the U.S. House of Representatives Foreign Relations Committee, who has consistently targeted China, believes thatYangtze River Storage appears to have violated U.S. Direct Products Abroad Rules (FDPR)。

In order to determine that Yangtze Storage really violated FDPR, the United States must prove that Yangtze Storage "knew" that its chips would be supplied to Huawei, which could be complicated.

In fact, last year, the United States pointed out thatYangtze River Storage will become China's "largest memory chip manufacturer".

Some Republicans, including Michael McCaul, also want to add Yangtze River Storage to the Commerce Department's "Entity List" and impose strict export control measures.

At the end of March this year, there was news that Yangtze River Storage successfully entered Apple's iPhone supply chain and will supply flash memory for Apple's iPhone SE 3, which also worried some US lawmakers.

As of now, Huawei and Yangtze River Storage have not publicly responded.
