The 2010 Review Conference on Nuclear Non-proliferation Treaty (NPT) reached consensus and approved a final document toward nuclear disarmament here Friday afternoon.

The final document, approved by 189 member nations of the treaty after month-long meeting since May 3, have agreed on measures toward disarmament and the establishment of a nuclear weapon-free zone in the Middle East.

This was the first agreement in a decade on the 40-year-old NPT, which has set the global agenda for preventing countries from developing nuclear weapons.

The 28-page final document said the five recognized nuclear- weapon states - Britain, China, France, Russia and the United States - commit to "accelerate concrete progress on the steps leading to nuclear disarmament," take steps to "further diminish the role and significance of nuclear weapons" and report back on progress by 2014.

"In implementing the unequivocal undertaking by the nuclear- weapon states to accomplish the total elimination of their nuclear arsenals, the nuclear-weapon states commit to undertake further efforts to reduce and ultimately eliminate all types of nuclear weapons, deployed and non-deployed" through various agreements, the document said.

The final document also called to the UN Secretary-General and co-sponsors of the 1995 Middle East Resolution to convene a conference in 2012, "to be attended by all states of the Middle East, on the establishment of a Middle East zone free of nuclear weapons and all other weapons of mass destruction."

It called on Israel to sign the NPT and to place "all its nuclear facilities under comprehensive safeguards of the International Atomic Energy Agency (IAEA)."

The document also urged the Democratic People's Republic of Korea to return "at an early date" to the six-party talks and to carry out obligations under the talks, which include China, the United States, Russia, the Republic of Korea and Japan as well.

Those obligations include the "complete and verifiable abandonment of all nuclear weapons and existing nuclear programs."

The NPT conference chairman, Philippine Ambassador Libran Cabactulan, said at the closing ceremony that the revised draft declaration was "carefully balanced" to reflect demands by all parties.

He said adoption of the declaration would allow "all the seeds of hope planted throughout the conference would bear fruit."

Egyptian Ambassador to the UN Maged Abdelaziz said on behalf of the 118-nation Non-Aligned Movement (NAM) that the NAM considered the document "an important step forward towards the realization of the goals and objectives" of the treaty.

On the issue of the Middle East nuclear-weapon free zone, he said the NAM countries intend to engage constructively with all concerned parties to implement the practical steps adopted in the final document.

"The road ahead is not easy but it's the only way forward," said Abdelaziz.

The review conference is convened every five years to review and advance the objectives of the NPT, under which nations without nuclear weapons committed not to acquire them; those with them committed to move toward their elimination; and all endorsed everyone's right to develop peaceful nuclear energy.

The last conference in 2005 was largely considered a failure as members were unable to agree on a number of issues nor produce a final document.

After the adoption of the final document, UN Secretary-General Ban Ki-moon issued a statement, welcoming the "successful outcome" of the conference.

"A strong spirit of compromise and cooperation has delivered a significant agreement to build a safer and more secure world," said Ban.

The statement said Ban "particularly welcomed" the agreement on a process leading to full implementation of the 1995 resolution on the establishment of a Middle East nuclear weapon-free zone.

He encouraged state parties to translate all of their commitments into concrete action so to realize the common goal of a world without nuclear weapons.
