Tombs of Chinese leader round American field (8)

I believe the answer is:

mausolea

'tombs' is the definition.
(mausoleum is a kind of tomb)

'chinese leader round american field' is the wordplay.
'chinese leader' becomes 'Mao' (Chairman Mao).
'round' means one lot of letters goes inside another.
'american' becomes 'US' (United States).
'field' becomes 'lea' (lea can mean a meadow or field of grass).
'mao' placed around 'us' is 'mauso'.
'mauso'+'lea'='MAUSOLEA'

'of' acts as a link.

(Another definition for mausolea that I've seen is " Stately tombs".)

I've seen this clue in The Times.
