This is one of the steps in fighting corruption and avoiding tax exemptions given to imported vehicles, he said at a regular Government meeting.
He said the ministries, sectors and state-owned agencies should strictly follow the standards and mechanisms on the use of automobiles as contained in Government Decision No. 32, which was issued in 2015.
He asked the Ministry of Finance (MoF) to review the total number of spare cars and allocate them to sectors and localities with real needs.
The MoF has also been asked to collaborate with the Ministry of Justice and the Government Inspectorate to investigate State-owned organisations and government officials that have received cars from private enterprises, and submit a report to the PM by April 28.
The PM urged the Finance Ministry to review the number of cars that have been written off by the State so as to ensure transparency of the process.
The ministry should make the management of State properties more effective by re-assessing current regulations and mechanisms and making due changes, he said.
The money earned from selling written-off cars should be sent to the State budget, he added.
Phuc also instructed the Ministry of Public Security (MoPS) to confiscate licence plates of written-off cars and report on the process of managing and using licence plates.
The MoPS will also be also responsible for collaborating with the finance and justice ministries to develop mechanisms for auctioning licence plates of written-off cars and report to the Government by May this year.
The PM asked the Ministry of Defence to review and confiscate Government licence plates issued to State enterprises that are not involved in national defence missions.
