The adoption of English medium instruction (EMI) in higher education has gained popularity in China's tertiary education as a result of globalization. International students in Chinese universities are celebrated as part of soft power projection to extend China's global impact. Informed by Piller and Cho's concept of "Neoliberalism as language policy" (2013) and Collins' "social reproduction theory" (2009, 2012), this study attempts to explore the EMI learning experiences of a cohort of international students at a border university in China. The policy documents, in-depth interviews, classroom observation, reflective journals and online interactions converge to reveal that, international students in EMI programmes experience exclusion and inequality despite the welcoming discourses of diversity. The paper highlights the necessity to pay attention to the ways in which higher education institutions reproduce inequalities of social stratification of international students through explicit and implicit institutional practices. It is argued that EMI policy in China's peripheral regions targeting international students from less-developed countries tends to perpetuate and accentuate educational inequalities. The study sheds light on a more inclusive pedagogical approach to alleviating international students' marginalisation and educating students of diverse linguistic, cultural, socioeconomic backgrounds for global citizenship in the context of China's Belt and Road Initiative.
