The Government of the Philippines is seeking USD537.4 million in loans from the Asian Infrastructure Investment Bank (AIIB) to finance works on the Manila Metro Rail Transit Line 4 (MRT-4). The loan will be up for final review by the fourth quarter of 2023.
In May 2023, it was announced that the cost of the mass transit project has increased from USD 1.06 billion to USD1.55 billion due to changes in the project design and technology. Construction works are expected to start by Q3 of 2024, with commercial operations scheduled in 2028.
