The Pentagon is urging Japan and Australia to clarify what role they would play if the US and China went to war over Taiwan, the Financial Times reported on Saturday. Elbridge Colby, the US under-secretary of defence for policy, has been pushing the matter during recent talks with defence officials of both countries, the report said, citing people familiar with the discussions.According to the newspaper, the reported request caught both Tokyo and Canberra off guard, as the US itself does not offer a blank cheque guarantee to defend Taiwan.Colby said in an X post that the department of defence is focused on implementing the president’s “America First” common sense agenda of restoring deterrence and achieving peace through strength, which “includes by urging allies to step up their defence spending and other efforts related to our collective defence.”The US is Taiwan’s most important arms supplier, despite a lack of formal diplomatic ties.REUTERS
