This thesis analyses a dialogue between the US ambassador to Zambia and two Zambian officials, regarding LGBT+ rights, following the sentencing of a same-sex couple by the Zambian high court. The theoretical framework utilizes postcolonial theory and a few of its concepts, namely cultural imperialism, and colonial discourses. To analyse the material, critical discourse analysis was conducted to examine if colonial discourse is present in the dialogue, and if so, how the discourses are used to reproduce or challenge the uneven power relationship between the West and Zambia. The thesis could conclude that discourses of cultural imperialism as well as colonial discourses were indeed present in the dialogue. The US ambassador reproduced the uneven power structure and the Zambian officials both reproduced as well as challenged it. The findings aim to contribute to the field of global LGBT+ advocacy, especially when conducted in a postcolonial context.
