'united' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?

'most of asian country viewable' is the wordplay.
'most of' means to remove the last letter.
'asian country' becomes 'India' (country in Asia).
'viewable' becomes 'visible' (I can't explain this - if you can you should give a lot more credence to this answer).
'india' with its final letter removed is 'indi'.
'indi'+'visible'='INDIVISIBLE'

'as' acts as a link.

(Another definition for indivisible that I've seen is " Unable to be separated".)
