Prime Minister Lee Hsien Loong has announced there will be a Haze Inter-Ministerial Committee, led by Minister Ng Eng Hen, to tackle the haze problem.
The Ministerial Committee will focus on "protecting public heath and safety, working with the Indonesians to mitigate the haze at source and maintaining economic and social resilience".
It will also review guidelines for protecting vulnerable groups and ensure that society and businesses, especially essential services, continue to operate.
Clear guidelines on the protective measures at each PSI threshold will be issued by the committee.
Mr Lee added that he will write to the Indonesian president to register Singapore's serious concerns and repeat the Republic's offers to help.
He also promised to take action against any Singapore companies or companies in Singapore responsible for causing the fires in Sumatra.
