The prime minister also pressed for intensified efforts to re-energise the UN General Assembly.
"We need to make more determined efforts to revitalise the General Assembly to enable it to fulfil its rightful role as the principal deliberative organ of the UN."
During his address, Dr Singh touched upon issues ranging from the financial meltdown to the global food crisis and situation in India's neighbourhood.
Welcoming the return of democracy in Pakistan, Dr Singh, who had a meeting with President Asif Ali Zardari in United Nations on Thursday, said India is committed to resolving all outstanding issues with Islamabad, including the Kashmir problem, through peaceful dialogue.
In the context of terrorism, he said the situation in Afghanistan is a matter of deep concern. "The international community must pool all its resources to ensure the success of Afghanistan's reconstruction efforts and its emergence as a moderate pluralistic and a democratic society."
Noting that the UN is a living symbol of pluralism, which has weathered many storms, the prime minister said it is the vehicle through which a combined will and efforts to address global challenges must be articulated and implemented.
