US President Barack Obama has outlined his vision of a new world order during his first address to the UN general assembly meeting in New York.

His vision was rooted in four basic principles: Non proliferation and disarmament, the promotion of peace and security, the preservation of the planet, and a global economy that advances opportunity for all people.

Among the speakers that followed were Muammar Gaddafi, the Libyan leader, and the UN secretary-general, Ban Ki-Moon.
