Argentina in the maze of international arbitration: a record number of arbitration claims and new concessions for investors
For over 20 years, Argentina had the world’s highest number of investor claims before international arbitration tribunals. It also has the highest number of bilateral investment treaties (BITs) in force in Latin America and the Caribbean (LAC).

The consequences could be a new wave of arbitration claims and increased external debt.
