US technology exports to Russia have failed by nearly 70 percent since sanctions began in late February, according to Raimondo, whose department oversees the export controls that form a big part of the sanctions package. Three dozen other countries have adopted similar export bans, which also apply to Belarus.
“Our approach was to deny Russia technology — technology that would cripple their ability to continue a military operation. And that is exactly what we are doing,” she said in a response to a question from Sen. Jeanne Shaheen (DN.H.) about the impact of the export controls.
The semiconductor anecdote came from Ukrainian officials, who told the secretary that when they opened up captured Russian tanks, they found parts from refrigerators and commercial and industrial machinery that appear to make up for other unavailable components, Commerce Department spokeswoman Robyn Patterson said.
The number of US shipments to Russia including items subject to the new rules — semiconductors, telecommunications equipment, lasers, avionics and maritime technology — has decreased 85 percent and their value has decreased 97 percent, compared with the same time period in 2021, Patterson said .
In her Senate remarks, Raimondo also pointed to recent reports that two Russian tank manufacturers have had to idle production because of a lack of components. The White House, too, has previously highlighted those reports, saying Uralvagonzavod and Chelyabinsk Tractor Plant have halted production.
Computer chips, also known as semiconductors, are the brains that operate most modern electronics, from appliances to fighter jets. Russia manufactures few of its own chips, historically relying on imports from Asian and Western companies.
The world’s biggest computer chip companies began cutting off deliveries to Russia in late February, after the US-led restrictions kicked in.
The United States and other Western nations already had regulated sales to Russia of chips and other electronic components specifically designed for military use. Those sales required a government license to proceed even before Russia’s recent invasion of Ukraine.
The new rules tightened those restrictions and also blocked the sale of most dual-use chips, which have both military and commercial applications, to nonmilitary users in Russia, including those in high-tech industries.
The Biden administration said the ban would cut off more than half of Russia’s high-tech imports and kneecap the country’s ability to diversify its economy and support its military. The ban was not designed to block deliveries of consumer electronics.
In a novel move that the United States has used only once before — against China’s Huawei — it is also requiring companies worldwide to abide by the rules and block such sales to Russia if they use US manufacturing equipment or software to produce chips. Most chip factories around the world use software or equipment designed in the United States, analysts say.
Previous research has shown Russia’s military has long relied on western electronics. Russian military drones shot down over Ukraine in recent years have been full of Western electronics and components, according to investigators from the London-based Conflict Armament Research group, which dissected the drones.
