Dacia has sent about 14,000 employees home on technical unemployment and Ford has also suspended work for its 6,000 employees.
Both plants implemented safety measures during the shutdown to curb the risk of COVID-19 infections and to ensure that their employees are protected against the new coronavirus.
Ford said it'll gradually resume output with about half of its workers in a single shift.
Dacia said that "production has been resumed on the Mioveni industrial platform, with the mechanical and chassis plant operating in three shifts."
The member state of the European Union, which recorded 13,512 coronavirus infections and 803 deaths, declared a 30-day state of emergency on 16 March and later extended it to 15 May.
