The star apple has been used for centuries and the Lo Ren star apple is a favourite variety with customers around the world.
The Vinh Kim Lo Ren Star Apple Co-operative exports more than 10 tonnes of star apples to the UK and Canada each year. It plans to ship 50 tonnes to Russia and Germany alone in 2012.
Businesses in the southern provinces are expanding to export the fruit to the US and other countries in Asia.
Vietnam is currently the only country in the world that is exporting the fruit. Other countries such as Cambodia, the Philippines, India, Thailand and Australia plant star apples only for domestic use.
