They discussed this in their July 29th, MD&A report:
Foreign Market Development Initiative: During June, 2010, the Company’s wholly owned subsidiary, Valcent Products EU Limited signed an agreement to supply a VertiCrop(TM) high density plant growing system to VF Innovations Ltd. (VFI), a new Hong Kong company specifically created to foster innovation in vertical farming. Valcent entered into discussions to form a Hong Kong-based partnership with VFI to manufacture and distribute the company's vertical growing systems for the Peoples Republic of China (PRC). The VertiCrop(TM) system was intended to sell fresh produce to the Hong Kong market and to serve as a demonstration unit for future customers and partners in the PRC as well as other segments of the Asian market. During ensuing negotiations, VFI decided not to proceed with the initiative, and as at the date of this report, the business relationship has been ended.
