Sri Lanka Prime Minister Ranil Wickremesinghe has said an economic crisis that has brought misery and unrest is "going to get worse before it gets better".
The country is facing fuel shortages and soaring food prices, with some Sri Lankans forced to skip meals.
Anger over the government's handling of the crisis has led to violent protests.
Ranil Wickremesinghe was appointed in an attempt to defuse the protests. It is the opposition MP's sixth stint as prime minister.
In his first interview since taking office, Mr Wickremesinghe said he would ensure families get three meals a day, reports BBC.
Appealing to the world for more financial help, he said "there won't be a hunger crisis, we will find food".
The new PM described the Sri Lankan economy as "broken", but he said his message to Sri Lankans was to "be patient, I will bring things back".
Wickremesinghe was sworn-in by President Gotabaya Rajapaksa on Thursday, but his appointment has largely been met with dismay, as he is seen as too close to the politically dominant Rajapaksa family.
In his interview, Wickremesinghe said he agreed with the sentiment of protestors who've been calling for President Rajapaksa to resign, but said that would not happen. "Blaming won't lead to action, I'm here to see people nourished," he said.
But he added that he was "going to change all the policies of the Rajapaksa government".
He also called on the international community for help.
"We need your assistance for a year, whatever we get from you we will repay. Help us to do it. We are the longest and oldest democracy in Asia," he said.
Sri Lanka's economy is in freefall. Food, medicine and fuel have run out or become unaffordable. Some people have died waiting at petrol stations to fill up their tanks.
