Five years ago, addressing the topical question of where the global development cause is headed, President Xi Jinping put forward the GDI at the General Debate of the 76th Session of the U.N. General Assembly. The GDI provided China's insight and contribution to reinvigorating global development. In just five years, it has turned from a Chinese proposal into a global consensus, and from a statement of goals into concrete actions in support of the SDGs, winning wide appreciation and drawing active participation from the international community.
