Language and culture play a critical role in international commercial relations. Since the 19th century, the English language has undeniably held the prominent position as the global lingua franca to facilitate communication between nations. However, China’s contemporary re-emergence as an economic superpower has expanded its global influence. Consequently, awareness of Chinese culture and language is becoming important not only globally, but also in the Caribbean, where China’s economic footprint has expanded considerably in recent years. This article conceptually explores the important role of language and culture within the growing Sino-Caribbean commercial relationship. Specifically, it discusses the potential impact of language on the trade and tourism sectors, which are two key industries that drive the economies of English-speaking Caribbean small island developing states. It does this by charting the development of the English and Chinese languages as dominant languages. It then briefly looks at the current level of Chinese engagement with the region in trade and, more contemporarily, the potential of greater Chinese tourism in the Caribbean. It discusses the value of deeper cultural and linguistic understanding in nurturing and expanding these relationships. Finally, the article concludes by providing meaningful recommendations on ways to mitigate cultural and linguistic barriers in order to promote deeper Sino-Caribbean trade and tourism.<br /><br />Key messages<br /><ul><li>Language and culture are two important factors in commercial relationships, especially trade and tourism.</li><br /><li>This article adds to the growing literature on budding Sino-Caribbean relations by exploring the importance of linguistic and cultural understanding to nurturing this relationship.</li><br /><li>It argues that Caribbean countries cannot take for granted that English will always be the lingua franca for Chinese-Caribbean relations given China’s expanding global footprint.</li><br /><li>The article makes recommendations on ways to mitigate linguistic and cultural barriers in order to deepen Sino-Caribbean commercial ties.</li></ul>
