The US, Britain, and Australia are considering expanding the AUKUS security pact to include Japan to counter China.

The expansion would focus on collaboration in developing advanced military technologies like quantum computing and artificial intelligence.

President Joe Biden is actively seeking to bolster alliances in Asia, with Japan potentially joining AUKUS as a significant partner.

An announcement about Japan's involvement in AUKUS may be forthcoming, coinciding with discussions between Biden and Japanese PM Fumio Kishida.

Australia expresses caution about initiating new ventures before substantial progress on nuclear-powered submarines is achieved.

China opposes the AUKUS expansion, citing the risk of triggering a regional arms race.
