Bangkok Metropolitan Administration (BMA) will establish a fund for the project to turn Bangkok into a paradise.
"The fund will be used most efficiently to tackle problems like garbage, pollution, traffic and drugs," BMA spokesman Chanin Rungsaeng said yesterday.
He said the fund would also be used to provide recreational activities, sports and education in the capital.
"We plan to complete the project within four years," he said, adding that the project to turn Bangkok into a paradise city was in line with HM the King Bhumibol Adulyadej's initiative.
