In short

  • The Straits Times states that Seatrium agreed to pay US$110 million under a deferred prosecution deal approved by the High Court in April.
  • The Straits Times notes that the alleged payments occurred between 2009 and 2014 and were linked to Operation Car Wash in Brazil.

What happened

On September 24, the State Courts granted Wong Weng Sun and Lee Fook Kang discharges amounting to acquittals after prosecutors decided to issue stern warnings instead of pursuing prosecution. The warnings, administered by CPIB on September 21, covered all charges related to alleged corruption in Sembcorp Marine’s Brazil business.

The charges stemmed from alleged bribery involving payments to Brazilian officials and attempts to remove incriminating emails, linked to Operation Car Wash. Separately, Seatrium (formerly Sembcorp Marine) entered a deferred prosecution agreement in July 2025, requiring a US$110 million penalty and compliance enhancements.

What compliance teams should check

  • Review the CPIB stern warnings issued on Sept 21 for Wong Weng Sun and Lee Fook Kang.
  • Update compliance controls in line with Seatrium’s deferred prosecution agreement requirements from July 2025.
  • Assess exposure to Operation Car Wash typologies involving payments to Petrobras officials between 2009 and 2014.

Why it matters

This case highlights the importance of robust compliance programs and the consequences of international bribery investigations. The acquittal of Wong Weng Sun and Lee Fook Kang, alongside Seatrium’s US$110 million penalty and compliance enhancements, underscores the need for vigilance in monitoring cross-border transactions and responding to regulatory actions. Compliance officers must stay alert to typologies from Operation Car Wash and ensure their organizations meet evolving legal and ethical standards.

How the radar works

Each item is classified by category, pinned to the jurisdictions it affects and scored from 0 to 10. The score starts from a model assessment of how serious the item is, then adds points for the kind of event, what it names and the source behind it. Reliability grades run from A1 (the regulator’s own notice) to C3 (a single secondary source).

AML News Radar reports what its sources publish. Summaries, categories and scores are automated; read the original notice before acting. It is not legal advice and not a screening decision.
