Old mother gets new land (4)
I believe the answer is:
oman
'land' is the definition.
(I know that Oman is Asian country)
'old mother gets new' is the wordplay.
'old' becomes 'o' (abbreviation).
'mother' becomes 'ma' (ma can mean mother).
'gets' says to put letters next to each other.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'o'+'ma'+'n'='OMAN'
(Other definitions for oman that I've seen before include "Arabian country, capital Muscat" , "Arabian peninsula country" , "Nation" , "Sultanate in southwest Asia" , "Former Gulf country, Muscat and --" .)
