The United States wants the United Nations to raise funding for refugees this year by 30 percent to $13 billion and says it will ask for the extra cash at a summit to be hosted by President Barack Obama in September.
U.S. Secretary of State John Kerry said the goal of the meeting, to be held on the sidelines of the U.N. General Assembly, would also be to at least double the number of refugees who are resettled or let in to other countries.
"This summit will be the culmination of a sustained, rigorous effort to rally the world community," Kerry said in a speech to the World Economic Forum in Davos.
He said it would also seek to get 10 more countries to help with the crisis and try to get a million refugee children into schools and a million refugees working legally.
"The private sector, civil society and religious organizations will also be called on to help integrate refugees into host communities socially, academically and through access to employment," Kerry said.
The United Nations said last month that the number of people forcibly displaced worldwide was likely to have "far surpassed" a record 60 million in 2015, mainly driven by the Syrian war and other protracted conflicts.
The estimated figure includes 20.2 million refugees fleeing wars and persecution, the most since 1992, the U.N. High Commissioner for Refugees (UNHCR) said in a report.
It said nearly 2.5 million asylum seekers have requests pending, with Germany, Russia and the United States receiving the highest numbers of the nearly one million new claims lodged in the first half of the year.
In his speech, Kerry attacked governmental corruption, saying it cost the global economy as much as $2.6 trillion a year, fueled militancy and demoralized populations. He cited Syria, Iraq, Nigeria and Ukraine as examples.
"We must deepen the fight against corruption - making it a first-order, national-security priority," he said, noting that it was imperative that the business community demand higher standards of behavior in dealings with governments.
A U.S. State Department statement said it would announce "significant new commitments" to help meet the new funding goal over the coming months and would "strongly encourage other nations to do the same".
