Australian Prime Minister Anthony Albanese said on Wednesday he will visit the United States to meet President Joe Biden after a trip to India this week.
"I look forward to the continuing engagement that I have with the US administration," Albanese told reporters before leaving for India, without giving a date for his US trip.
The Sydney Morning Herald reported on Tuesday that Albanese would meet with Biden and Sunak in San Diego on Monday to unveil new details of the 2021 AUKUS pact, which was conceived as part of efforts to counter China in the Indo-Pacific region.
Australia's ambassador to the United States Arthur Sinodinos said last week that details of the submarine deal would be announced in mid-March.
While the United States and Britain have agreed to provide Australia with the technology to deploy nuclear-powered submarines, the three allies have yet to say exactly how the capability will be transferred to Australia, which does not have a nuclear-propulsion industry, Reuters reported.
AUKUS will be Australia's biggest-ever defense project and offers the prospect of jobs in all three countries, but it remains unclear whether it will involve a US or a British-designed submarine, or a combination of both, or when the vessels will become operational.
