Arms control campaigners and human rights advocates say one person every minute dies worldwide as a result of armed violence, and that a treaty is needed to halt the uncontrolled flow of weapons and ammunition that they argue helps fuel wars, atrocities and rights abuses.
The UN General Assembly voted in December to relaunch negotiations this week on what could become the first global treaty to regulate the world's $70 billion trade for all conventional weapons -- from naval ships, tanks and attack helicopters to handguns and assault rifles -- after a drafting conference in July 2012 collapsed because the United States, then Russia and China, wanted more time.
Delegates to the July conference said that Washington had wanted to push the issue past the November 2012 presidential election, though the administration of President Barack Obama denied that. The current negotiations will run through March 28.
The United States says it wants a strong treaty. But Obama is under pressure from the powerful National Rifle Association, the leading US pro-gun group, to block the pact. The group has vowed to torpedo the convention's Senate ratification if Washington backs it at the United Nations.
US Secretary of State John Kerry voiced conditional support for the treaty on Friday, saying Washington was "steadfast in its commitment to achieve a strong and effective Arms Trade Treaty that helps address the adverse effects of the international arms trade on global peace and stability."
But he repeated that the United States -- the world's No. 1 arms manufacturer -- would not accept a treaty that imposed new limits on US citizens' right to bear arms, a sensitive political issue in the United States.
The NRA has dismissed suggestions that a December US school shooting massacre in Connecticut bolstered the case for a global arms pact. It has also warned that the treaty would undermine US citizens' right to own guns, a position that supporters of the treaty say is false.
The American Bar Association, an attorneys' lobbying group, last month disputed the NRA position, saying in a paper "ratification of the treaty would not infringe upon rights guaranteed by the Second Amendment."Ammo: 'The fuel of conflict'
The point of the treaty is to set standards for all cross-border transfers of any type of conventional weapon -- light and heavy. It also would set binding requirements for nations to review all cross-border arms contracts to ensure the munitions will not be used in human rights abuses, do not violate embargoes and are not illegally diverted.
Diplomats say that if the treaty conference fails to reach the required consensus because the United States, Russia or another major arms producer opposes it, nations can still put the draft treaty to a vote in the UN General Assembly.
The other alternative is to amend the draft to make it acceptable to the US and other delegations. But supporters of the treaty fear that could lead to a weak and meaningless pact.
"The US traditionally has an allergy to treaties," a European diplomat told Reuters. "It might be better to have a good treaty without the US and hope they come around later."
The treaty focuses solely on international arms transfers. If a pact is approved in New York, it will require ratification by national legislatures before it can take effect.
UN Secretary-General Ban Ki-moon called for a pact "that regulates international transfers of both weapons and ammunition and provides for common standards for exporting states."
"These standards are important for assessing the risks that transferred weapons are not used to fuel conflict, arm criminals or abet violations of international humanitarian or human rights law," he said.
Negotiations over the next two weeks will not be easy, UN diplomats say. Washington opposes inclusion of ammunition in the treaty. Rights groups and arms control advocates hope the US delegation will compromise on the question of ammunition.
"Ammunition is literally the fuel of conflict," said Roy Isbister of Saferworld, a peace lobby group. "Without ammunition, the guns fall silent."
Rights groups have urged delegations to repair loopholes in the current draft treaty, which they say could leave avenues for abusers of human rights to continue getting weapons.
They say the partial coverage of ammunition in the current draft is a major weakness. Rights groups say that the global ammunition industry for small arms and light weapons is worth $4.3 billion, with 12 billion bullets produced each year.
UNITED NATIONS (Reuters) -- Negotiators from around 150 countries gather in New York on Monday for a final push to hammer out a binding international treaty to end unregulated conventional arms sales, a pact that a powerful US pro-gun lobby is urging Washington to reject.
