The current study used Structural Equation Modeling (SEM) as a statistical technique to test a hypothesized mediating model to uncover the underlying relationship between the L2 motivational self-system, L2 anxiety, and L2 willingness to communicate (L2 WTC). This study is significant because it considers the unique experiences of English as a foreign language (EFL) learner in the era of globalization by incorporating the L2 motivational self-system. The mediating effect of L2 anxiety was also accounted for, providing a deeper understanding of how emotional factors influence L2 WTC. The data were collected through a questionnaire administered to 260 students at six public universities in China. The results showed that (a) two subcomponents of the L2 motivational self-system (ideal L2 self and L2 learning experience) were positive predictors to L2 WTC; (b) the higher the degree to which learners were motivated by their ought-to L2 self, the higher the anxiety of English learning; and (c) L2 anxiety had a suppressing effect between the L2 motivational self-system and L2 WTC. Specifically, L2 anxiety weakens the direct positive effect of the L2 motivational self-system on L2 WTC, leading to a decrease in L2 WTC. Pedagogical implications and future research directions were also addressed.
