World leaders want to spend 30 billion euros to help save the lives of women and children over the next five years.
A United Nations summit in New York identified maternal and child health as its two Millennium Development Goals that require the most work.
UN Secretary General Ban Ki-Moon told delegates that the strategy would save as many as 16 million lives worldwide.
He said spending on women and children reduces poverty and stimulates growth and is a fundamental human right.
Both developed and developing countries have contributed to the drive.
The foundations of the world’s richest men, Mexican tycoon Carlos Slim and Microsoft billionaire Bill Gates, were among the contributors.
Officials say they expect more pledges to be made within the five-year time frame.
