US President Joe Biden sought on Tuesday to rally the international community to meet the challenges of our time, telling world leaders "we cannot afford to waste any more time."

Biden spoke to a number of pressing challenges faced by the global order, from the coronavirus pandemic to the ravages of climate change, maintaining the US will "do our part" to meet them, but maintaining the world would be more "successful and more impactful if all nations are working toward the full mission to which we are called."

- As a global community we are challenged by urgent and looming crises where lie enormous opportunities if, if we can summon the will and resolve to seize these opportunities - he said during the 76th General Assembly.

The president also dashed authoritarian governments the world over, saying they are stifling the wills of their people and would ultimately fail to end the age of democratic governance.

- The future will belong to those who unleash the future of their people, not those who stifle it. The future will belong to those who give their people the ability to breathe free, not those who seek to suffocate their people with an iron hand - he said.

- The authoritarians of the world may seek to proclaim the end of the age of democracy, but they’re wrong. The truth is the democratic world is everywhere - he added.
