More than 120 presidents, prime ministers, kings and potentates will take part in the 69th annual United Nations General Assembly special debate, which will start on September 24 at UN headquarters in New York City.
A number of issues will get discussed during the debate, including ISIS, Ebola virus and Ukraine. Ban Ki-moon, the eighth and current Secretary General of the United Nations, affirmed that countries are battling so many issues. Every issue requires an independent approach, he said.
President Barack Obama's main focus will be terrorism. He will chair a Security Council meeting on ISIS and the threats posed by foreign fighters. America is expecting to get a unanimous approval to take up a resolution that all countries will take strict action against their citizens who join ISIS and other militant groups.
The countries should ban them from returning as they can act as a big threat to their native nations. Moon praised the increasing international consensus to act against the threat to global peace and security. He has also welcomed the commitment of the US to fight against terrorism.
Other looming challenges include Ebola, which is spreading across West Africa. Secretary General Ban warns, "This has gone beyond heath issues. It has gone to the areas of affecting social and economic situations. It may affect the political stability if not properly contained and properly treated".
It has happened for the first time a health issue has led to UN emergency sessions. Also, the outbreak requires quick response so that the spread can be stopped. For it, more funds, expert services and anti-Ebola supplies will be required.
Tensions between Ukraine and Russia have lessened, but many leaders are still concerned over the latter's future intentions.
Renovations that were underway at the UN complex are almost complete. The General Assembly hall has been modernized.
