特朗普签署行政令宣布国家紧急状态，禁止外国产电网大功率设备在美采购安装

President Donald Trump signed an executive order on Wednesday declaring a ​national emergency and banning the use of some foreign equipment ‌in the U.S. electricity grid, the White House said.

The order cites what the White House described as an "unusual and extraordinary foreign threat" posed by foreign-made bulk-power systems that may ​present national security vulnerabilities.

Trump's order, the latest example of Washington's ​approach to tackling technology threats posed by China, follows a ⁠decision by the European Commission earlier this year to ban ​Chinese-made inverters from publicly funded energy projects.

Last year, Reuters reported that ​rogue communication devices not listed in product documents had been found in some Chinese solar power inverters by U.S. experts who strip down equipment hooked up ​to grids to check for security issues.

"I ... find that the ​situation with respect to the foreign supply of bulk-power system electric equipment constitutes ‌an ⁠unusual and extraordinary threat, which has its source in whole or substantial part outside the United States, to the national security, foreign policy, and economy of the United States and hereby declare a ​national emergency with ​respect to that ⁠threat," Trump said in the order.

Under the order, certain foreign-produced bulk-power system electric equipment, including associated critical ​software and digital capabilities that could pose cybersecurity or ​operational ⁠risks, will be barred from being purchased or installed in the United States, the White House said in a statement.

The order also asks the U.S. ⁠Energy ​Secretary to impose conditions on the continued ​use and operation of such equipment to address concerns identified by the Trump administration, ​the White House added.
