Which one of the following launched the 'Nature Solutions Finance Hub for Asia and the Pacific'?

The Asian Development Bank (ADB) launched the 'Nature Solutions Finance Hub for Asia and the Pacific' at COP27 to scale up nature-based solutions and mobilize private capital for biodiversity and climate action across the region. While the Asian Infrastructure Investment Bank (AIIB) is a major regional player, it focuses primarily on infrastructure development and was not the lead entity for this specific environmental finance initiative. The core concept being tested is the specific mandate and recent environmental initiatives of Multilateral Development Banks (MDBs) operating in the Asia-Pacific region.
