The new wage will come into effect on April 1, Jarin Chakkapak, permanent secretary of the Labour Ministry, who chaired the tripartite minimum wage committee, said on Wednesday after the meeting.
Phuket, Chon Buri and Rayong will have the highest daily minimum wage of Bt330, while Bangkok and surrounding provinces will have the second highest of Bt325.
Workers' representatives who attended the meeting expressed satisfaction with the new rates.
The nationwide minimum wage was raised from Bt300 to Bt310 last year after remaining static for three years from 2014 to 2016.
After the increase, the average minimum wage will be Bt315.97 per day.
Jarin said he would propose the hike to Labour Minister Pol General Adul Saengsingkaew before submitting it to the Cabinet.
