Abstract: As technology advances, interstate communication has become faster. The use of the telegraph made it possible to send messages over long distances in a shorter time, and another breakthrough occurred with the advent of the telephone in the 1870s by Alexander Graham Bell and also the advent of radio technology that revolutionized communication. Radio communication enabled states to engage not only their citizens on foreign policy issues, but also the foreign public. In the same way, the use of fax increased the speed of sending written information. On the other hand, the use of the telephone increased the indulgence of countries towards summit diplomacy, where directors participate in direct conversations with their colleagues and reduced the need to send envoys, but also speeded up communication by reducing diplomatic bureaucracy.
