From a reductionist view, economic diplomacy in a pre-digital economy means diplomatic activities to develop exports and attract foreign investments. In recent years, the issue of «digital economy diplomacy» has been raised, including the possibility of using innovative companies and digital technologies at international levels and attracting capital and development. The basis of this diplomacy relies upon the principle that the technological power of a country in the era of Industry 4.0 depends on its technol companies’ ability to enter the international competition scene. This is necessary for the digital economy, where technology and innovation, or in other words, digital transformation by virtue of Big data, become a new source of economic value creation and power as such.
