The US government says it has revoked some licences that allowed US chip makers to export certain goods to Chinese technology giant Huawei.
The Department of Commerce did not specify which permits were cancelled but the move follows Huawei's release of an AI-enabled computer powered by a chip created by Intel.
American chip maker Intel declined to comment to a request for comment from BBC News. The BBC has also contacted Huawei and San Diego-based chip giant Qualcomm for responses to the announcement.
Since 2019, the US has restricted technology exports, such as computer chips, to Huawei, citing alleged ties to the Chinese military.
"We have revoked certain licenses for exports to Huawei," the Commerce Department said in a statement on Tuesday, but did not give details of which permits had been withdrawn.
Some US lawmakers had criticised the administration of President Joe Biden following the launch last month of Huawei's MateBook X Pro laptop.
