Papua New Guinea's government is under scrutiny for importing 40 luxury Maserati cars from Italy for the upcoming Asia-Pacific Economic Cooperation (Apec) summit, BBC reports.
The Quattroporte sedans, which cost more than $100,000 each (£75,000), will be used by foreign leaders.
Media and activists have questioned if the poor Pacific country has wasted millions.
But the government says the private sector has "committed" to paying.
Apec Minister Justin Tkatchenko said the cars would "provide the level of carriage for leaders that is the standard for vehicles used at Apec summits".
Pictures of the cars arriving at Port Moresby airport on chartered cargo planes were shared on social media and sparked concern that taxpayer money was being wasted on the lavish purchase.
