The UN general assembly is set to discuss the prospects for peace and security in a special session on Monday.
Key issues will be raised at the conference, which is expected to include a joint session on Syria and a second session on the situation in Afghanistan.
The two sessions are expected to address issues including the worsening humanitarian situation in South Sudan, the spread of deadly infectious diseases in Afghanistan and Afghanistan’s role in the crisis.
In a statement, UN Secretary General Antonio Guterres said the world would not be the same without peace and stability.
“For too long, conflict and instability have ravaged nations, destabilised economies and threatened the world,” Guterre said.
“Now, more than ever, we must seize the moment and forge a brighter future.
To that end, I call upon all those who can lead and to that end I invite the leaders of the world to come together in the hall of the UN to renew the world’s hopes for a more peaceful and prosperous future.”
Guterres also urged the world not to forget the suffering that has been endured by its peoples.
“The UN has been at the forefront of the struggle for justice and peace, and we have seen the results of that struggle.
And now, I am confident that peace and reconciliation will prevail and lead to the end of conflict, poverty and injustice,” he said.
