More than 50 countries have pledged 30,000 troops for United Nations peacekeeping at a US summit called to shore up missions under strain from the rise in global crises.
China scaled up its contribution, taking the lead in setting up an 8000-strong stand-by police force while Colombia made a first-time offer of up to 5000 troops.
The pledges represent a major boost to UN peacekeeping, which relies on voluntary contributions from UN member states to run its 16 mission worldwide.
US President Barack Obama told leaders that peace operations were "experiencing unprecedented strains" and deployed in "more difficult and deadlier conflicts".
"We know that peace operations are not the solution to every problem," Obama told the summit held on the sidelines of the UN General Assembly.
"But they do remain one of the world's most important tools to address armed conflict," he said.
The new contributions include helicopters, engineering units, field hospitals and bomb-detonating expertise that are desperately needed to bolster UN peace missions.
A key player in peacekeeping in Africa, Rwanda offered two attack helicopters, two field hospitals, an all-female police unit and 1600 new troops.
Indonesia boosted its participation with training and 2700 new troops while India pledged 850 additional troops.
British Prime Minister David Cameron announced 70 troops for the UN-African Union mission in Somalia and up to 300 troops for the UN mission in South Sudan, which is grappling with one of the world's worst humanitarian crises.
There were also pledges from Armenia, Finland, Ghana, Mexico, South Korea, Sri Lanka, Vietnam and Uganda.
The United States had hoped to draw more pledges from European countries that have gradually pulled their troops out of peacekeeping and contributed to the NATO-led mission in Afghanistan.
But the European pledges remained modest.
In contrast, China - which has strong economic interests in Africa - offered more engineering soldiers, transport and medical staff and pledged to train 2000 peacekeepers from other countries to carry out de-mining operations.
Boosting troop contributions will help the United Nations tackle a wave of sexual abuse allegations that have hit its missions, notably in the Central African Republic.
The new commitments will give Secretary-General Ban Ki-moon the leeway to remove units whose soldiers face accusations and replace them without weakening a mission.
