In September 2017, Taichung, Taiwan, OTA has signed the Memorandum of Understanding for cooperation among six flower auction markets from the Netherlands, Brazil, China, Australia, Taiwan and Japan. The international flower auction group is organized by AIPH (Association Internationale des Producteurs de l’Horticulture) which is a global association of horticultural producers from 25 countries.

In favor of growers and buyers, all members promise to commit to building a platform to exchange knowledge and technology, and to strengthening development of sustainability. The group plans to continue periodical talks about those matters.
