JAKARTA: Indonesia’s disaster chief on Thursday defended the country’s efforts to fight forest fires that have blanketed Southeast Asia in choking haze, and said he believed rains would arrive within a month to finally douse the blazes.

“Are we able to manage the fires? The answer is clearly a yes... we are not overwhelmed, we can manage it and there is progress,” National Disaster Management Agency chief Willem Rampangilei told reporters.

Malaysia, Singapore and large expanses of Indonesia have suffered for weeks from acrid smoke billowing from fires on plantations and peatlands that are being illegally cleared by burning. Singapore has offered to help in fighting the fires but Rampangilei said it was not needed.

“Indonesia welcomes the offer but at this moment, everything is under control,” he said.

“We can see some achievements, some progress that we have successfully extinguished a number of fires,” he added.

More than 20,000 troops, police and other personnel have been sent to Sumatra and Kalimantan to fight the fires through waterbombing and chemically inducing rainfall.
