Three trademarks of farmer-scientist Ho Quang Cua for ST24 and ST25 rice were officially granted trademark protection titles in Australia on September 27.

Agricultural engineer/business man Ho Quang Cua's attempt to trademark ST25 rice in UK and US markets has succeeded within a few months, bringing good news for millions of Vietnamese farmers.

Four foreign companies have registered trademark protection for Vietnam’s ST25 rice in the U.S., which may choke off Vietnamese food exporters tapping the market later, according to Vu Ba Phu, director of the Trade Promotion Department under the Ministry of Industry and Trade.
