This paper focuses on the lesson topics in two business Chinese textbooks, Delicious Business Chinese and New Silk Road: Elementary Business Chinese Fast Track (China), aiming to explore their similarities and differences in topic selection, content organization, and cultural integration. First, an in-depth analysis of the lesson themes in both textbooks is conducted, examining how they present business scenarios, negotiation strategies, and cultural exchanges. Second, through comparative analysis, the study reveals that the Korean edition emphasizes integration with Korean corporate culture and workplace etiquette, paying special attention to the practical needs and cultural background of Korean learners. In contrast, the Chinese edition highlights the characteristics of the Chinese market and business operation processes. Furthermore, the paper investigates how these differences in topics influence learners’ cross-cultural business communication. Finally, based on the findings, the paper offers recommendations on how to balance the localization needs of learners in developing business Chinese textbooks, providing a reference for future textbook compilation and optimization.
