A key factor to the security of all NATO countries is our unity, President Rumen Radev said upon arrival for the Alliance's summit in Brussels.

The Bulgarian head of state has pointed out that NATO's development plan until 2030 has set high goals. President Radev expressed satisfaction that the plan includes measures aimed at overcoming the technology gap between NATO members that he had spoken about before. "I am extremely satisfied because the projects we are going to discuss today are a key for preserving the technological advantage of the Alliance and are of great importance for the development of the defense industry of Bulgaria, our scientific potential, private initiative and start-up ecosystems," the Bulgarian President added.
