The Natural Resources and Environment Ministry will inform neighbouring country Indonesia that land clearing and forest fires in central Sumatra have brought haze to some parts of Malaysia.

Its minister, Wan Junaidi Tuanku Jaafar, said he would send an official letter to Indonesian Environment and Forestry Minister Siti Nurbaya Bakar on the matter.

"We will inform her that we see the haze already reaching some parts of Peninsular Malaysia and Sarawak," he told reporters after officiating at the national-level International Day for the Conservation of Mangrove Ecosystem 2016 in Kuala Sepetang in Taiping today.

Wan Junaidi said although Indonesia had acted fast to put out the forest fires, the smoke could not be prevented from causing haze.

"Now they are quick (to extinguish the fires) when they get the indicators of fire outbreaks, unlike before, indicating that they are implementing what they had promised," he said, adding that the haze hitting Malaysia had not reached unhealthy levels yet.

According to the Department of Environment website, as at 3pm today, 33 areas recorded moderate Air Pollutant Index (API) readings.

API readings of 0-50 indicate good air quality, 51-100 (moderate), 101-200 (unhealthy), 201-300 very unhealthy, and 300 and above (hazardous).
