In a speech to political authorities in the country - home to hundreds of tribal groups and more than 800 spoken languages - the 87-year-old Catholic pontiff made a heartfelt appeal for an end to a spate of ethnic violence that has killed dozens in recent months.
Visiting as part of an ambitious 12-day trip to four countries, the Pope said PNG's natural resources were "destined by God" for the whole community.
May the Kingdom of God find full acceptance in this land, so that all the peoples of Papua New Guinea, with the rich variety of their traditions, may live together in harmony and offer the world a sign of fraternity. — Pope Francis (@Pontifex) #ApostolicJourneySeptember 7, 2024
"Even if outside experts and large international companies must be involved in the harnessing of these resources, it is only right that the needs of local people are given due consideration when distributing the proceeds and employing workers, in order to improve their living conditions," he said on Saturday.
The Pope said natural resources should be developed in a sustainable manner that "improves the wellbeing of all, excluding nobody, through ... international co-operation, mutual respect and agreements beneficial to all parties".
Arriving for his speech at the APEC Haus, a conference centre built for the 2018 Asia-Pacific Economic Co-operation forum, Francis was greeted with a dance from a group of Papua New Guineans wearing traditional outfits featuring feathered headdresses and beaded skirts.
The Pope, who uses a wheelchair due to knee and back pain, was rolled past an entry foyer with a curved timber screen inspired by a typical lakatoi tattoo design.
In a speech welcoming Francis, PNG Governor-General Bob Dadae thanked the Pope for his humanitarian advocacy and called the Catholic Church one of the country's "key development partners".
PNG contains some of the largest known gold deposits and is a major exporter of natural gas and oil.
The government, led by Prime Minister James Marape since 2019, has sought to boost local benefits from projects undertaken by international conglomerates such as Exxon Mobil Corp and Newcrest Mining.
An economic update in May said growth in the country was a modest 2.7 per cent in 2023.

Home to hundreds of tribes, PNG has a long history of ethnic warfare.
Violent attacks in three remote villages in July likely killed at least 26, according to the United Nations.
Francis on Saturday said it was his "particular hope that tribal violence will come to an end".
He said he was appealing "to everyone's sense of responsibility to stop the spiral of violence and instead resolutely embark on the path that leads to fruitful co-operation".
He called for a "definitive solution" to the status of Bougainville Island, the largest island in the Solomon Islands archipelago.
Currently an autonomous region of PNG, the island voted overwhelmingly for independence in 2019 but years of political deadlock in PNG's parliament have stalled the vote's ratification.
A sprawling country of mountains, jungle and rivers, PNG has a population estimated at anywhere from nine million to 17 million.
The Vatican estimates there are about 2.5 million Catholics in the country.
Francis landed in PNG on Friday evening, after a trip to Indonesia, and will stay until Monday.
He will then visit East Timor and Singapore before heading back to Rome on September 13.
It is his longest overseas trip yet.
