Prime Minister Peter O'Neill has met with Tonga's high commissioner, Princess Angelika Latufuipeka Tukuah, at which he raised the prospect of increased labour mobility between the countries and increasing investment opportunities.
"We are all mindful that we are facing challenging economic circumstances around the region, so our support to Tonga will be guided by current economic conditions, and it will be carefully targeted.
"We are committed to helping Tonga ensure that the 2019 Pacific Games will be a great success," O'Neill told Princess Angelika.
"There has been growing Papua New Guinean investment around the Pacific, in countries that include Samoa, Fiji, Solomon Islands, Vanuatu, and we would like to see this investment expand to Tonga.
"An important part of expanding business connections is increasing air services, and around the Pacific, through code sharing agreements with local airlines, we are opening up flights between our countries."
O'Neill said labour mobility should be advanced. "We would like to see more people from Tonga come to Papua New Guinea, to share their skills and knowledge with our people, and strengthen our cultural interaction. I will continue to advance labour mobility issues with our partners and through regional forums including APEC and the Pacific Islands' Forum," O'Neill said.
