ZTE has said that a US ban on the sale of parts and software to the company is unfair and threatens its survival, and vowed to safeguard its interests through all legal means.
The United States has imposed a ban on sales by American companies to ZTE for seven years, saying the Chinese company had broken a settlement agreement with repeated false statements - a move that threatens to cut off its supply chain.
"It is unacceptable that BIS insists on unfairly imposing the most severe penalty on ZTE even before the completion of investigation of facts," ZTE said in its first response since the ban was announced, referring to the US Commerce Department's Bureau of Industry and Security.
"The Denial Order will not only severely impact the survival and development of ZTE, but will also cause damages to all partners of ZTE including a large number of U.S. companies," ZTE said in a statement.
ZTE said it regards compliance as the cornerstone of its strategy, adding it invested US$50 million in export control compliance projects in 2017 and plans to invest more this year.
A senior US Commerce Department official said earlier this week that it is unlikely to lift the ban.
"We're going to have to see how this unfolds. But there is no provision currently for that to occur," the official said, who declined to be identified due to the sensitivity of the matter.
The Commerce Department has an appeals process for companies to try to get off the list, but it is unclear whether that would be available to ZTE because the case had been previously subject to a settlement, according to people familiar with the matter.
Even so, ZTE would have little recourse in the near term because appeals would have to be approved by the Bureau of Industry and Security, the same agency that issued the ban.
Companies must submit appeals to a committee that would issue a ruling within 30 days, according to the agency's website.
ZTE said it will not give up efforts to solve problems through communication, and it is determined to take judicial measures to protect the legal rights and interests of the company.
The ban has ratcheted up tensions between China and the United States at a time when they have already threatened each other with tens of billions of dollars in tariffs, fanning worries of a full-blown trade war that.
In China, there has been a patriotic backlash with an outpouring of support for ZTE on social media and most domestic newspapers have chosen to put the lion's share of the blame for ZTE's troubles on the country's heavy reliance on foreign semiconductors.
Meanwhile, the US government is considering using an emergency law to restrict Chinese investments in sensitive US technologies, a senior Treasury official said.
Trade in ZTE shares has been suspended since Tuesday. As of Monday's close, they were worth some US$19 billion.
