WASHINGTON — The acting budget chief for the White House has called for a two-year delay of part of a federal measure that is aimed at Huawei Technologies, the Chinese telecom giant.

The measure targeting Huawei was included in the National Defense Authorization Act for the current fiscal year and bars government agencies from contracting with Huawei or with companies that use its equipment.

Russell T. Vought, the acting director of the Office of Management and Budget, said enacting the ban within one year, as planned, would cause too much burden for American companies. He also sought to delay a rule prohibiting federal grant and loan recipients from using Huawei equipment, an action that particularly hits rural telecommunications providers.

“This is about ensuring that companies who do business with the U.S. government or receive federal grants and loans have time to extricate themselves from doing business with Huawei and other Chinese tech companies” that are covered by the law, said Jacob Wood, a spokesman for the budget office.
