No prize for seeing that a percentage of those would do export only. WHA is not export only anyway.
I know when i was exporting food to China many years ago, i had zero to do with the local market. That was taken care of.


The headline number from the current release is that in 2014-15 there were 51,228 exporters of goods and/or services. That represented an increase of 4,160 (or nine per cent) from 2013-14. Within that total, the number of goods exporters increased by 3,947 (nine per cent) to 48,681 while the number of services exporters increased by 260 (eight per cent) to 3,557³.
By sector, the number of goods exporters is dominated by wholesale trade (12,912 exporters or about 27 per cent of all goods exporters), manufacturing (9,306 exporters, 19 per cent), and retail trade (4,261 exporters, nine per cent).
