This analysis aims to assess the impacts of Chinese investment in Cambodia by drawing on data in the form of new reports, commentaries, analyses, and articles published on different media platforms and in academic journals. Taking Sihanoukville as a case study, the analysis shows that, despite economic benefits, Chinese investments have significant negative impacts on Cambodia as a host country of foreign direct investment. Four dimensions of the impact, including political, socio-cultural, environmental, and socio-economic are discussed.
