The main idea of this paper is to provide a reader with a concrete idea about International Trade Barriers and how it influences on the trade. Why do countries need a barrier and the main types of trade barriers? This study is generally a non-empirical analysis. The main sources of this study include secondary sources like textbooks, reports, relevant national and online documents and some publications. In this paper, I would also like to discuss Trade facilitation in Central Asia. The existing situation with trade in Asia and the ways of improvement.
