Abstract: The Kenya-Somalia diplomatic rift and ongoing territorial dispute significantly impact Kenyan trade and commerce relations. While there is existing knowledge about the dispute and its implications, key aspects still require further investigation to understand the extent and specific consequences on Kenyan trade fully. This study aimed to determine the effects of the Kenya-Somalia diplomatic rift on Kenyan trade and commerce relations with Somalia between 2012 and 2021. This study period was selected because it is a historical period when transited transformed into a Federal State and boldly reclaimed control of her international affairs. The objectives of the study was to examine the effects of the Kenya-Somalia diplomatic rift on the Miraa trade between Kenya and Somalia. The research design used in the study was descriptive. The study was conducted in Nairobi City County and stratified sampling was appropriate for the study. The primary data collection method used in this study was questionnaires. Most respondents agreed, and the results show that diplomatic rifts and their resolution can profitably embrace an institutional approach that sanitizes us to benefit from well-defined borders together. The possibility of such benefits impacted the choice to resolve the unresolved border issue amicably to foster better relations that favor unresolved trade and peaceful coexistence. The government should implement regulations and initiatives designed to deter young people from engaging in the production and trade of miraa.
