Purpose: This paper aims to examine the participation experiences of a sample of Chinese teacher trainees and their Finnish teacher trainer on an in-service teacher training program exported from Finland to Beijing, China. Design/Approach/Methods: Six science teachers from Beijing and their Finnish teacher trainer participated in semi-structured interviews. From the ideological perspective of international education, a total of eight semi-structured interviews were analyzed through qualitative content analysis. Findings: The results show that all interviewees were highly motivated to learn from the Other's education system and culture. Some participants benefited from a broader understanding of the Self's and the Other's education systems, while others did not. The interviewees also described some participation challenges, such as language barriers and practices that adapted learner-centered teaching approaches in Beijing schools. Furthermore, the interviewees mentioned future expectations of more in-depth communication between Finland and China. Originality/Value: Some recommendations for better training outcomes, improving the quality of participation experiences, and reaching more mutual understandings were discussed at the end of this study.
