Here is a newly (days ago?) declassified SECRET/"NOFORN" (ie. US Eyes Only) document titled "A Free and Open Indo-Pacific". It is a US national security briefing prepared by White House staff.
The document contains a Cover Letter and US National Security Council further action description that were missing when the "000174" Attachment was released by the White House on January 5, 2021.
The White House released the whole document on January 13, 2021 to one Australian media outlet. The US aim may be mainly to show Trump/the White House did have a working Indo-Pacific alliance strategy after all.
Reading the document reveals the alliance objective is mainly to contain China.
India, Japan, Australia, North and South Korea, Taiwan, Philippines and Thailand are all mentioned in this document. It is useful to use the search function in it - to identify country mentions.
Here is an Australian ABC News summary of its import https://www.abc.net.au/news/2021-01-12/details-of-trump-administrations-indo-pacific-strategy-revealed/13052216.
