The deal has won the “Pioneering Spirit Award” at the 2025 Global Restructuring Review Awards.
  • Represented Sunac China Holdings Limited (Sunac) in the restructuring of its US$10.2 billion offshore debt.

The deal was recognized as the “Restructuring Deal of the Year” by IFLR Asia-Pacific Awards 2024.
