The Institute has established extensive scientific and technological cooperation and exchanges with agricultural research institutes and universities in more than 20 countries, including the United States, the Netherlands, Japan and France, as well as international institutions such as the United Nations Development Programme (UNDP), the International Potato Center (CIP) and the International Biodiversity Center. He has presided over projects such as soilless cultivation of vegetables and improvement of potato breeding ability aided by the United Nations Development Programme, participated in the application of biotechnology in genetic improvement of rape and the cultivation of eggplant breeding materials resistant to fungal and bacterial diseases by protoplast culture technology in the European Union, and presided over more than 60 projects such as genome research on micronutrient quality characteristics of Chinese cabbage crops and potatoes beneficial to human health and potato genome sequencing planned by the Sino-Dutch strategic science alliance. "Sino-Dutch Horticultural Crop Genome Analysis Laboratory" was established. Cooperative breeding of Chinese cabbage, tomato and cucumber was carried out with vegetable seed companies such as Saint Denis in the United States and Longjing in Japan.

By the end of 2007, the institute had sent nearly 600 people abroad for short-term study and visit, and invited more than 500 experts and scholars from 39 countries and regions such as the United States and the Netherlands to visit and give lectures. Several international training courses on vegetables and flowers in developing countries have been held successively. International academic conferences such as "Genetic Resources of Horticultural Crops", "Variety Improvement of Horticultural Crops" and "Application of Biotechnology in Horticultural Crops" were jointly held with China Horticultural Society.
