The focus of this study was to investigate the relationship between rural development and community relations strategies in south-east Nigeria. The purpose was to determine how the availability of improved healthcare infrastructure affects rural communities to access it, as well as how events sponsorship affects the cultural advancement of the ground host community. The study, which focused on the south-east Nigerian states of Abia, Enugu, and Imo, used a survey research design. A purposive sample technique was used to select 400 individuals. Cronbach Alpha was used to verify the reliability of the tool after a pilot survey was used to collect data. Regression was used to test hypotheses as part of the data analysis process, which also included descriptive and inferential statistics. The findings showed that access to better healthcare was positively and significantly impacted by the availability of health infrastructure. Furthermore, it was found that the focus on corporate event sponsorship significantly helps in the cultural advancement of rural communities. The study came to the conclusion that the interaction between corporate entities and rural development significantly shapes the socioeconomic structure of the area. Among the recommendations was a call for companies to make investments in all-encompassing health infrastructure in order to improve access to healthcare in rural areas. In addition, companies hoping to foster cultural development in rural areas were encouraged to actively support and take part in community events.
