The National Legislative Assembly has voted 183-0 to pass a 150-billion-baht supplementary expenditure budget for fiscal 2018 ending in October.
Of the total supplementary budget, 67%, or 100 billion baht, will be additional expenses for state agencies and state enterprises while 49.6 billion will go to repaying Treasury reserve.
Finance Minister Somkid Jatusripitak told the NLA the extra spending would focus on strengthening the economy.
Some 24 billion baht will go to restructuring farm production while 76 billion baht will create career opportunities and employment in the provinces.
"We forecast the economy would expand in a range between 3.6% and 4.6% from 3.9% in the previous year, he said.
