伊朗外交部长：与美国的会谈和信息交流仍在进行。

Australian Deputy Prime Minister and Defence Minister Richard Marles confirmed on the 31st that Australia will be unable to purchase newly built US Virginia-class nuclear submarines under the prior procurement agreement and will instead receive US in-service Virginia-class boats. Under the US-UK-Australia trilateral security partnership (AUKUS), Canberra had planned from the 2030s to acquire two US in-service Virginia-class submarines plus one newly built, improved Virginia-class boat. Marles said the adjustment will age Australia’s submarine fleet but could relieve pressure on US shipbuilding capacity.
