If all these countries join it makes me wonder of the AUKUS is turning into a Pacific version of NATO to counter China:

The United States, Britain and Australia are considering South Korea, Canada and New Zealand as potential partners for cooperation on advanced capability projects of their AUKUS security partnership, a senior U.S. official said Tuesday.

The remarks came a day after the defense chiefs of the three countries issued a joint statement noting their consideration of Japan as a partner for Pillar II projects of the partnership.

Launched in September 2021 in an apparent move to counter China’s assertiveness, AUKUS consists of two key pillars. Pillar I is to support Australia in acquiring conventionally armed, nuclear-powered submarines, while Pillar II is for cooperation in high-tech areas, including quantum computing, artificial intelligence and hypersonics.

“The AUKUS partners are considering a range of additional partners who may bring unique strengths to Pillar 2, including the ROK, Canada and New Zealand, in addition to Japan,” the official said in response to a question from Yonhap News Agency. ROK stands for South Korea’s official name, the Republic of Korea.
