The United Nations has launched an appeal for $US543 million for Pakistan.
More than 2 million people have been displaced by fighting in the Swat Valley in Northwest Frontier Province.
The appeal on Friday came a day after donors promised $US224 million, including $US110 million from the United States.
The military began an offensive in the Swat Valley and neighbouring districts on 2 May to stop the spread of a Taliban insurgency.
Nearly 1.7 million people have been displaced by the offensive. About 555,000 people were forced from their homes by earlier fighting in the region.
