Republic of Azerbaijan and Republic of Serbia have established diplomatic relations 25 years ago, in 1997. Ever since, Serbia and Azerbaijan have nurtured intensive and outstanding bilateral relations, which are continually improved to mutual satisfaction. The issue of commemorative postal stamps “25 Years of Diplomatic Relations Between Republic of Serbia and Republic of Azerbaijan” reflects extraordinary relations between the two friendly countries, but also contributes to their further advancement. The symbolism of paired architectural achievements of the two countries in the area of spirituality, culture and economy, which characterises this issue, highlights the important fields of cooperation between the two countries, but also the common shared values which put the successful economy in the foreground, at the same time relying on spirituality and culture as sources and guarantees of preservation and permanent building of the national identity.
