The UN is appealing for $160m (£136m) emergency funds to help Pakistan cope with the devastating floods.
More than 1,150 people were killed and nearly half a million displaced in the disaster.
“Pakistan is awash in suffering,” UN Secretary-General Antonio Guterres said in a video message launching the appeal.
“Pakistani people are facing a monsoon on steroids…people’s hopes and dreams have been shattered.”
The floods affected more than 33 million people, or one in seven Pakistanis.
The Pakistani authorities, supported by the army, rescuers and volunteers, are fighting against the consequences of the floods.
Although rainfall stopped three days ago and floodwaters have receded in some areas, large areas remain under water.
Rescuers were evacuating stranded people to safer ground, including makeshift tent camps that have sprung up along highways, villages and towns.
Early government estimates say the devastation caused $10m (£8.5m) in damage to the economy, however, Planning Minister Ahsan Iqbal said it was of a preliminary estimate and that the actual cost would be “much higher”. .
On Monday, the board of the International Monetary Fund approved the release of $1.17 billion (£1 billion) for Pakistan.
It’s part of a bailout deal the IMF and Pakistan signed in 2019, but the release of a $1.17 billion tranche was put on hold this year after the IMF raised concerns about Pakistan’s compliance with the terms of the agreement under the government of Imran Khan.
Last week the UN allocated $3m (£2.5m) to aid agencies and their partners to respond to the floods, with the money being used for health, nutrition, food security, water and sanitation.
Pakistani Climate Minister Sherry Rehman said on Monday that new monsoons were expected in September.
While monsoons are common at this time of year in the region, they hit earlier than usual in Pakistan, officials say.
All of Pakistan has been affected by the latest floods
Massive rains last week affected almost the whole country, and while Pakistan is used to monsoon rains and floods, Ms Rehman said, but not like this.
The flooding has the hallmarks of a natural disaster fueled by climate change, but it is too early to blame global warming, experts said.
“This year, Pakistan has received the highest rainfall in at least three decades. So far this year, the rain is more than 780% above average levels,” said Abid Qaiyum Suleri, executive director of Sustainable Development Policy Institute and member. of the Climate Change Council of Pakistan.
“Extreme weather events are becoming more frequent in the region, and Pakistan is no exception.”

Pakistan experienced floods and similar damage in 2010 that killed nearly 2,000 people, but the government failed to implement plans to prevent future floods by preventing construction and homes in flood-prone areas and riverbeds, said Suleri.
Floods and monsoon rains have damaged a million homes and affected 33 million people and reflect how poorer countries can often pay the price for climate change in large part caused by more industrialized nations.
Since 1959, Pakistan has been responsible for just 0.4% of historic global CO2 emissions, while the US is responsible for 21.5%, China 16.5% and the EU 15% .
According to the National Disaster Management Authority, at least 498,000 people in the country of 220 million people are in relief camps after being displaced.
