France's Macron says Australia PM lied over submarine deal

French President Emmanuel Macron said Australian Prime Minister Scott Morrison lied to him over the cancellation of a submarine building contract in September, and indicated more efforts were required to rebuild trust between the two allies.

In Rome for the G20 summit, the two leaders were meeting for the first time since Australia scrapped the multi-billion dollar deal with France as part of a new security alliance with Britain and the United States unveiled in September.

The alliance, dubbed AUKUS, which could give Australia access to nuclear-powered submarines, caught Paris off guard, prompting it to recall ambassadors from Washington and Canberra amid accusations that France had been betrayed.

"I don't think, I know," Macron said in response to a question whether he thought that Morrison had lied to him

"I have a lot of respect for your country," he said in comments on Sunday to a group of Australian reporters who had travelled to Italy for the summit of leaders of the top 20 economies.

"I have a lot of respect and a lot of friendship for your people. I just say when we have respect, you have to be true and you have to behave in line, and consistently, with this value."

Morrison told a media conference later the same day that he had not lied, and had previously explained to Macron that conventional submarines would no longer meet Australia's needs. The process of repairing ties had begun, he added.

Morrison and Macron spoke last week before the Australian prime minister publicly sought a handshake with his French counterpart at the G20 meeting.

On Monday, Australian Deputy Prime Minister Barnaby Joyce urged France to view the matter in perspective.

"We didn’t steal an island, we didn’t deface the Eiffel Tower. It was a contract," Joyce told reporters in Moree, 644 km northwest of Sydney.

"Contracts have terms and conditions, and one of those terms and conditions and propositions is that you might get out of the contract."

Joyce spoke just hours before Australian Foreign Minister Marise Payne met France's ambassador to Canberra. Payne said their hour-long meeting focused on efforts to repair the relationship.

On Friday, US President Joe Biden said the handling of the new pact had been clumsy, adding that he had thought France had been informed of the contract cancellation before the pact was announced.
