With the development of social media, nowadays, people connect to each other more frequently and timely. In this article, we want to discuss this interactive communication in Chinese social media, i.e., WeChat, Weibo and Xianhongshu, between the Chinese immigrants in France (French Chinese) and Chinese in China. The intent of this article is to explore if there is a significant difference between high-acculturated and low-acculturated French Chinese in the use of word-of-mouth (WOM) in response to the purchase of product categories high in social signaling value. The article helps firms plan their international marketing strategy in terms of how they will benefit from WOM where French Chinese consumers comprise a significant part of the target market. Additionally, this research helps firms develop effective virtual interaction tools to build a strong long-term brand relationship with ethnic groups.
