Leaders of key multilateral development banks recently took part in Global Infrastructure Forum 2017 to determine how to best work with private-sector clients and entire countries to create more sustainable infrastructure.

The forum brought together potential investors, representatives of the United Nations and leaders from African Development Bank, Asian Development Bank, Asian Infrastructure Investment Bank, European Bank for Reconstruction and Development (EBRD) and a number of other key banks from around the world, according to an EBRD press release.

The forum covered topics important to nations around the world, such as roadways, water lines and electrical power that are scarce in some developing countries. Getting the private sector involved in financing such infrastructure projects can help lead to better long-term investments and returns, according to the release.

Some of the speakers at the event included Amina Mohammed, deputy secretary general of the United Nations and Wolfgang Schauble, Germany's finance minister.
