In this study, we analyzed the cultural elements presented in Korean language textbooks published during various stages of Korean language education in China. This analysis spans from the initial phase through the adjustment phase into the period immediately before the development phase, with a specific focus on changes across these periods. Overall, in textbooks, Chinese culture was represented more prominently than North Korean culture. Regarding North Korean culture, elements related to history, politics, and economy were prominently featured in the initial phase, demonstrating the superiority of the North Korean system, as well as advocating for the Workers’ Party and Chairman Kim Il-sung. Nevertheless, this emphasis diminished considerably in later periods. Conversely, concerning Chinese culture, elements related to politics, history, values, and economy exhibited a declining trend. This decline indicates a gradual reduction of support for the Communist Party and key leaders as well as ideological orientations and the emphasis on Sino-North Korean friendly relations. Furthermore, textbooks from the period immediately before the development included frequent presentations of geography and daily life culture aimed at showcasing societal progress. These evolving patterns observed in Korean language textbooks published in China can be interpreted as a reflection of the political and diplomatic shifts between North Korea and China, as well as societal developments.
