The leaders pledged to work for a reinvigorated and strengthened multilateral system, rooted in the purposes and principles of the UN Charter and international law, with renewed institutions and a reformed governance that is more representative and effective.

They also pledged to reform the UN Security Council through a transformative reform that aligns it with the realities and demands of the 21st century and makes it more representative, inclusive and effective.
