Research background: The economy with the strongest influence on world affairs, international politics and world economy is undoubtedly the economy of the United States of America. In the Czech Republic, after the revolution, the USA quickly came to the forefront of interest and mutual foreign trade grew significantly. However, their global influence was significantly reflected not only in economic aspects, but also in sociological aspects. In recent years, the so-called “Americanization” has been taking place in the Czech Republic. American terms were often adopted in the commonly used Czech language, and the demand for American goods increased significantly. Purpose of the article: The objective of the presented text is to evaluate development of the influence of the USA on the economy of the Czech Republic by analysing the development of key macroeconomic quantities, in particular gross domestic product, gross national product, balance of payments and foreign trade. Based on the results of this analysis, the future development of the Czech economy, more precisely opportunities and impacts arising from mutual trade relations between the American and Czech economies, is predicated. Methods: Descriptive statistic. Findings & Value added: The results of the research showed a gradual expansion of the influence of the American economy in the Czech Republic, which began after 1989 and continues to this day. This influence manifested itself in several aspects. It was reflected in the structure of mutual foreign trade, and also in the Czech culture and the Czech language (adoption of English terms into the Czech language). The further potential of mutual trade is highlighted out by comparing the structure of export and import from the USA in total and export and import from the USA to the Czech Republic.

Research background: The People’s Republic of China in the 21st century can be described as an economy with high growth rates and great ambitions. Some statistics even indicate that China will become the world’s new hegemon by 2040. The People’s Republic of China is not only one of the largest exporters but is increasingly speaking to the world economy and international relations. Since the beginning of the 1990s, mutual relations between the People’s Republic of China and the Czech Republic can be described as very good and constantly deepening, which can be evidenced, among other things, by the number of trade agreements. Purpose of the article: Purpose of the article is to evaluate a development of mutual relations between Czech and Chinese economies in order to predict their future development. Emphasis will be placed on the development of mutual trade through the evaluation of absolute and relative indicators and growth rates. Methods: The paper is based on secondary data from the database of the Czech Statistical Office. The key methods used in the article are the analysis of time series of real products of the Czech Republic and China and their foreign trade. The analysis focuses on the trend, deviations and development of absolute and relative indicators. Findings & Value added: The results of the analysis proved that the Chinese economy is growing on average more than twice as fast as the Czech economy. Because of that, the economic/living standards of the population of both countries are converging. The growth rate of the People’s Republic of China, together with its high spending on science and research, means that (if this trend is maintained) China is likely to become the world’s new hegemon in the near future.
