In Asia the chances to sell the 728JET should be limited. China is a country where some might be sold.
Vietnam Airlines is a possibility I can think about, they have said serveral times that they want to enlarge their fleet so either 2nd-hand F70s or new 70-seaters could be in the race.
UNI Air, Taiwan, has been rumoured to be interested in some 728JET but I haven´t heard anything about them for quite some time.
In Indonesia I see some need for a replacement of the old F28s, several dozends are still flying there.
InAustralia, Qantas is looking on the 728JET/ERJ-170 and the newly launched RJX. Best chances: RJX, followed by the 728JET and the last the ERJs.
