Thailand has exported longan to international market more than four decades, and China is the main international market. After Thailand and China agreed the ASEAN framework under Free Trade Agreement (FTA) since 2003, the average volume and value of longan export per year during 2004-2010, grow up to 200,000 tons and 2,737 million Baht respectively. And the average of growth rate per year of volume and value is 18%, 15%. Therefore, the objectives of the research aim to investigate the supply chain performance, collaborative supply chain of exported longan and impact factors under Thailand-China FTA. The results are based upon empirical studies, a grower and an exporter. The questionnaires developed by Q-sort technique, have been intensively employed in order to collect data. As a significant result; this paper finds exporters have high level out of eight factors, it illustrates that good competence in business for this part of supply chain as well as are well-packed and much stronger than the grower. Nevertheless, the results from regression analysis also confirm the relationship of factors in all four models. From these experimental results, both international business and agriculture business have to be emphasized in order to manage longan export.
