The ministries decided not to use the petrol and oil price stabilisation fund.
Since the beginning of this year, petrol prices have undergone 35 adjustments, with 18 up, 13 down, and four unchanged.
The price adjustment is intended to ensure that the fluctuation of petrol and gas prices in the country is in line with changes in prices in the world while encouraging the use of biofuel as well as minimising negative impact on socio-economic development, production and business activities, among others.
