Vietnam has about 5,000 hectares of star apple fruits, mostly in the Mekong Delta, yielding 60,000 tonnes each year.
The provincial People’s Committee has pledged to help improve infrastructure to boost the market, while companies themselves are also striving to upgrade standards.
It is understood that Cat Tuong Agricultural Products Producing & Processing invested packaging and preserving facilities to meet stringent US rules.
It also secured deals with farmers to ensure a steady supply of the fruits.

Aroundy one of every four fresh apples grown in the US is exported. The top export markets are Mexico, Canada, India, Taiwan, United Arab Emirates, Hong Kong and, ironically, Vietnam.
