SINGAPORE - While the primary ability to act lies with the Indonesians, the Singapore Attorney-General is investigating what can be done against firms involved in causing the haze, Foreign Minister K. Shanmugam said on Saturday.
"We will offer no succour or refuge if the actions of the companies have been deemed illegal in Indonesia and impacted on Singapore," he said during a briefing to reporters.
The stern warning came a day after the Indonesian government named some firms in Riau province involved in the blazes, and which have Singapore links.
The minister pointed out that "serious" issues of jurisdiction and international law need to be considered, so he has asked the Attorney-General to look into what can be done to such companies if there is proof that they contributed to the haze.
Mr Shanmugam, who also holds the Law portfolio, said he expects to know what Singapore "can or cannot do by this weekend".
But the primary ability to act lies with the Indonesians as the firms are located there, he stressed.
"We would like to see strong, firm, effective action taken against them in Indonesia, because that's where they are, that's where the actions are taking place, that's where their offices are, the senior people.
"We'd really like to see firm, quick action and any assistance we can render in that respect, we will do so."
