SINGAPORE – On Oct 23, the National Environment Agency (NEA) issued notices to 10 Singapore-based firms under the Republic’s haze law.
This marks Singapore’s widening probe into companies believed to be linked to the transboundary haze choking the region. NEA also issued legal notices to 10 Indonesian firms earlier in October.
Of the Singapore companies, some responded to the notices within a day of receiving them, saying they would cooperate with the authorities.
Senior Minister K. Shanmugam warned on Oct 19 that errant firms will no longer be allowed to hide behind complex corporate structures or geographical borders to evade responsibility, and that the Republic is ready to use “every legal and regulatory lever” to confront them.
Using corporate documents and filings, The Straits Times takes a deeper look at these Singapore companies.
Sinar Mas
Three of the 10 firms issued NEA notices on Oct 23 are subsidiaries of Sinar Mas, a conglomerate with businesses in eight sectors, including agroforestry, telecommunications, energy and real estate development.
They are APP Company, APP Company (China) and Golden Agri International.
The conglomerate is under the control of the Widjaja family, with an estimated net worth of US$28.3 billion (S$36.1 billion).
In 2025, Forbes placed the Widjajas in third place out of Indonesia’s top 50 richest individuals and families.

APP Company (China)
APP had been linked to the haze during the 2015 crisis as well.
Back then, three of its Indonesian pulpwood suppliers had been issued preventive measures notices under Section 9 of Singapore’s haze law by the NEA. Their cases were never closed.
These three – Bumi Andalas Permai, Bumi Mekar Hijau and Sebangun Bumi Andalas Wood Industries – were again issued such notices in 2026. Another supplier, Buana Megatama Jaya, was also implicated in 2026.
A fifth Indonesian firm that received a Section 9 notice from NEA in 2026, Baratama Putra Perkasa, may also have ties to APP.
ST reported on Oct 20 that its beneficial owner, Lee Mon Lun, was listed as a director and chairman of the board for Greenrich Group, a logging company in Cambodia.
Greenrich Group does not appear anywhere on APP’s website, but its public relations manager in 2020 was quoted in Cambodian news outlets as saying the firm is an APP subsidiary.
According to APP’s financial statement for 2025, it recorded an operating profit of US$1.65 billion. Some of its popular brands include Paseo and Nice.
Corporate registry filings reveal that APP Company lists Japanese national Kunihiko Naito and Indonesian national Suresh Kilam as directors.
APP China lists Singaporean Jennifer Loy Huey Ling and Singapore permanent resident Linda Suryasari Wijaya Limantara as directors. Linda is a scion of the Widjaja family.
Leading APP Group’s sustainability committee is Bernard Tan, a former brigadier-general who served as chief of armour in the Singapore Armed Forces and previously helmed the Football Association of Singapore. He is also the former country head for DBS Bank in Indonesia and former marketing head of ST Engineering.
