The main difference between these two terms is that public relations focuses more on external communication and corporate image, whereas corporate communications encompasses all communication, both internal and external.

Public relations focuses on how companies and organizations are presented to the outside world. The process of targeted creation and dissemination of messages to shape the public image and perception is managed here.

Corporate communication, on the other hand, refers to all communication within a company, both internal and external. This includes the way in which internal communication takes place and how the company effectively conveys its goals and messages to its employees. External communication with stakeholders, customers and the public is also taken into account.
