UN chief Ban Ki-moon said the heads of state, civil society leaders and CEOs will seek to address issues like the "horrendous violence" in Syria and Iraq, "where conflict and governance failures have provided a breeding ground for extremist groups" as well as the situation in Mali, South Sudan, Ukraine and Libya.
"We will not let these crises be forgotten - and we will meet next week at the highest level to determine what more we can do," Ban said yesterday ahead of the UN General Assembly beginning September 24.
Modi will address the world body on September 27.
Ahead of the General Debate, Ban will host nearly 120 heads of state for his one-day climate change summit on September 23 to mobilise political will for a universal and meaningful climate agreement next year in Paris and to generate ambitious steps to reduce greenhouse gas emissions and strengthen resilience.
"Action on climate change is urgent. The more we delay, the more we will pay in lives and money," he said.
"At this time of turmoil, the next two weeks will highlight again the indispensable role of the United Nations in tackling global threats and seizing opportunities for common progress," he said.
Ban said he is anticipating an "impressive turnout" of leaders and "significant commitments and progress.
