More than 130 U.S. companies have reportedly applied to sell to Huawei, but the Commerce Department has approved none of them

Trump said in July that some U.S. suppliers would be allowed to sell to Huawei while it remains blacklisted, but so far no vendors have been allowed to do so. Reuters reports that more than 130 applications have been submitted by companies that want to do business with Huawei, but the U.S. Commerce Department has not approved any of them yet.

Huawei has served as a bargaining chip in the U.S.-China trade war, which escalated again last week when Trump said he would adds tariffs to $550 billion worth of Chinese imports, after China said it would impose duties of $75 billions on U.S. goods. Trump's mixed signals during this weekend's G7 summit also created confusion on Wall Street.

When both presidents met at the G20 Summit in June, Donald Trump told Chinese leader Xi Jinping that he would allow some American companies to sell to Huawei, even though it remains on the Commerce Department's Entity List. Secretary of Commerce Wilbur Ross said the Commerce Department would begin accepting applications again, requiring companies to prove that the tech they sell to Huawei would not pose a national security risk.

But one of the reasons no licenses have been granted yet is because the Commerce Department is unclear about what it is supposed to do. Former Commerce department official William Reinsch told Reuters that "nobody in the executive branch knows what [Trump] wants and they're all afraid to make a decision without knowing that."

In addition to providing telecom equipment, Huawei is an important customer for many U.S. tech firms, including Qualcomm, Intel and Micron. Out of the $70 billion in parts it bought last year, $11 billion of that went to U.S. suppliers. The U.S. claims Huawei is a national security risk, a charge the company has repeatedly denied.
