Through the grant of UNESCO IPDC (International Programme for the Development of Communication), Cambodian Journalists Alliance Association (CamboJA) has been implementing a project to strengthen Cambodian journalists’ alliance capacity on investigative journalism to promote media pluralism, freedom of expression, and access to information in Cambodia. Under this project, a five-day training on investigative journalism has been organised to build the capacity of journalists in Cambodia to produce critical and investigative stories, using the UNESCO’s “Story-based Inquiry: a manual for investigative journalists” as a training guide. Upon the training, the participants have also received mentorship support from experienced journalists to put the lessons into practice.
