Vessel knocked over by a hostess, disheartened Asian dignitaries (6)

'asian dignitaries' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps there's a link between them I don't understand?

'vessel knocked over by a hostess disheartened' is the wordplay.
'vessel' becomes 'jar' (type of container).
'knocked over' shows that the letters should be reversed in order.
'by' says to put letters next to each other.
'disheartened' says to hollow out the word (remove centre letters) (the middle or heart is removed).
'hostess' with its middle removed is 'hs'.
'jar' back-to-front is 'raj'.
'raj'+'a'+'hs'='RAJAHS'
