Meng Wanzhou, the CFO of Huawei Technologies has reportedly returned to work at the tech giant's headquarters in Shenzhen.
The report on Monday (October 25) comes after almost three years fighting extradition to the U.S. in Canada.
Her return to the day job was reported by state-backed Chinese newspaper Global Times.
Meng is the daughter of Huawei's founder.
She completed three weeks of quarantine last week after returning to Shenzhen.
On arrival back in China, she was greeted by a crowd of well-wishers chanting patriotic slogans.
The extradition drama had been a central source of discord between Beijing and Washington.
Chinese officials had signalled that the case had to be dropped to help end a diplomatic stalemate.
Meng was detained in December 2018 in Vancouver after a New York court issued an arrest warrant.
She was accused of trying to cover up attempts by Huawei-linked companies to sell equipment to Iran in breach of U.S. sanctions.
Last month she reached an agreement with U.S. prosecutors to end a bank fraud case against her.
