The extension of temporary relief is good news for ZTE, which has been scrambling to cope with the potential damage on its global operations and brand image from its alleged export-control violation.
In April, the company replaced three of its most senior executives, including its chief executive.
The U.S. imposed trade sanctions on ZTE in early March, alleging the company violated rules restricting exports of U.S. technological goods to Iran.
The move hindered the Chinese company s ability to procure U.S. components and software and created tension between Beijing and Washington.
The PwC team is led by Jeannette Chu, who had previously worked for the Commerce Department as a policy adviser on export control and foreign policy issues, the person said.
ZTE, which is based in the southern Chinese city of Shenzhen, is a major manufacturer of mobile phones and telecom-networking equipment like base stations.
