Nearly 3,000 products from across China with geographical indications are showcased at a trade fair in Guangzhou that opened on Saturday and will last for a month. The exhibits include fruits, tea, vegetables, aquatic products, traditional medicines, handicrafts and flowers, all marked with their place of origin. The organizer of the event said that although China has abundant resources with geographical indications, their value has been overlooked, and the market for such products needs further development.
