There are two purposes of this bachelor's thesis. The first one is to outline the shape of economic diplomacy of the Czech republic, more precisely Czechoslovakia, during the 20th century to the present state. On the grounds of gained data and information I intended mainly to defend the opinion that despite significantly deliberalized market since the early 50s there was institutional support for research and analytical activities, this country had a team of experts in the field and it is wrong marking this subcategory of diplomacy as an activity arisen recently. In the second half I focus more strongly on the CzechTrade agency as a representative of trade promotion. Initially, the company is briefly characterized, in the last chapter, its activities in key export markets are analyzed. BRICs countries were selected as examples of these markets, however, in-depth analysis is dedicated only to two of the countries, namely Brazil and India, because of limited range. The reason for my choice is enormous potential BRICs generally evince, the short-selection is influenced by less awareness of Brazilian and Indian markets compared to Chinese and Russian markets. Individual economies are defined by brief characteristics, form of mutual trade including its commodity structure as well as projects and services through which CzechTrade operates in a specific market. At the very end, the impact of agency's activities in these countries is summarized in terms of entering and doing business in the market.
