Dujarric had said that the UN General Assembly session is the "World Cup of diplomacy. It's the Oscars of diplomacy. It's also an interesting fashion week."
The week will kick off with a summit on September 19 to address large movements of refugees and migrants. This is the first time the General Assembly has called for a summit at the Heads of State and Government level on this topic to come up with a blueprint for a better international response.
World leaders are expected to adopt a political declaration as an outcome document at the summit, during which the UN will see a new addition to its family — a dedicated migration agency.
Leaders of the UN and the International Organisation for Migration (IOM) will sign an agreement to officially make IOM a related agency of the UN system.

On September 21, the Assembly will hold a high-level meeting on antimicrobial resistance, which has become one of the biggest threats to global health and endangers other major priorities, such as human development.
On the same day, the Secretary-General will make a pitch for an early entry into force of the Paris Agreement on climate change by convening a special event at which countries can deposit their ratification instruments with him.
To date, it will require 28 more countries, representing 16 per cent of global emissions, to ratify the Agreement, which was reached last December.
The new President of the General Assembly Peter Thomson had said in his maiden address that Security Council reform will be among the focus areas during his term.
"Reform of the UN Security Council is also work at hand for the 71st session (of the UN General Assembly). The membership is unanimous in agreeing that reform is necessary to align the Security Council with the realities of the 21st Century," Thomson had said this week.
The war in Syria will also take centre stage during the high level week with world leaders taking stock of the cessation of hostilities in the troubled country.
According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), Syria is one of the most complex and dynamic humanitarian crises in the world today.
Since March 2011, more than a quarter of a million Syrians have been killed and over one million injured.
Another 4.8 million Syrians have been forced to leave the country, and 6.5 million are internally displaced, making Syria the largest displacement crisis globally.
The US and Russia are the co-chairs of the international grouping known as the ISSG, which comprises the UN, the Arab League, the European Union and 16 other countries, and has been involved in efforts to resolve the conflict.
"While many conflicts are causing enormous pain, none is causing so much death, destruction and widespread instability as the worsening war in Syria," Ban had said as he welcomed the reinstatement of the Cessation of Hostilities following the understanding reached between the Russia and the US.
Thomson had said mobilising international support to combat violent extremism and terrorism will also be the focus during the upcoming high-level Assembly session.
"Building on the review of the Global Counter-Terrorism strategy, including the Secretary-General's Plan of Action on The Secretary-General's Plan of Action to Prevent Violent Extremism, we will act on improving the UN architecture to face these threats.
"In these troubled times, no community is immune from violent extremism and terrorism. We face this scourge together and must find the solutions together," Thomson added.
