據路透社報道，美國極端議員正在敦促拜登政府進一步限制向中國公司銷售芯片制造工具，他們希望能夠對中國公司事實類似華為這樣的限制。
在給美國商務部長吉娜·雷蒙多的一封信中，極端代表Michael McCaul和參議員Tom Cotton表示，企業要獲得美國許可才能將使用美國技術在國外制造的半導體出售給華為的規定，應適用于任何設計14納米或以下先進芯片的中國企業。
這封信的日期為4月13日，于周四公開。該信尋求銷售電子設計自動化（EDA）軟件的許可，以及對與中國公司進行芯片相關銷售的其他限制。
信中說，這些行動將確保美國公司以及合作伙伴和盟國的公司不得中國出售相關工具。
商務部的一位代表在確認收到這封信后指出，上周有七個中國超級計算實體被列入了貿易黑名單。這位人士說，該機構“正在不斷審查情況，以確定是否有必要采取進一步行動。”
去年，美國頒布了一項規則，要求海外任何使用美國芯片制造設備生產的企業，如果想向華為銷售半導體，則必須先向美國獲取許可證口。
華為在2019年被美國商務部列入“實體清單”。在一開始，該黑名單限制了美國供應商對華為的銷售，但并未打擊國外制造的商用芯片。但后來，美國擴大了《外國直接產品規定》，該規定要求使用美國技術或軟件企業要遵守美國法規。

Congressional China hawks are urging the Biden administration to restrict sales of chip-making tools to Chinese companies, similar to an action taken against telecommunications equipment maker Huawei Technologies Co （HWT.UL）。
In a letter to U.S. Commerce Secretary Gina Raimondo, Representative Michael McCaul and Senator Tom Cotton said the rule that requires U.S. licenses to sell semiconductors made abroad with U.S. technology to Huawei should apply to any Chinese company designing more advanced chips at 14-nanometers or below.
The letter, which is dated April 13 and was made public on Thursday, seeks licenses for the sale of electronic design automation （EDA） software, among other curbs on chip-related sales to Chinese companies.
The actions would “ensure U.S. companies as well as those from partner and allied countries are not permitted to sell the communists the rope they will use to hang us all,” the letter said.
A representative of the Commerce Department, acknowledging receipt of the letter, noted that seven Chinese supercomputing entities were placed on a trade blacklist last week.
The agency is “continually reviewing circumstances to determine whether additional actions are warranted,” the person said.
The United States last year issued a rule requiring licenses for sales of semiconductors to Huawei made overseas with U.S. chip-making equipment, expanding its reach to halt exports to the company.
Huawei was added to the Commerce Department's “entity list” in 2019 over national security and foreign policy concerns.
The blacklisting restricted sales to Huawei from U.S. suppliers, but did not crack down on commercially available chips made abroad. In response, the United States expanded the Foreign Direct Product Rule, which subjects foreign-made goods based on U.S. technology or software to U.S. regulations, for Huawei.
This week's letter was sent after Tianjin Phytium Information Technology and six other Chinese supercomputing entities were placed on the entity list for supporting military modernization efforts.
Cotton and McCaul want to not only restrict U.S. sales to Phytium, but to require a license for any company that uses American tools to make a Phytium-designed semiconductor chip.
Anything short, they said, “would be a half measure masquerading as a forceful action.”
