In the midst of dangerous circumstances and events and the thorny relations between Syria and Lebanon ,the issue of Syrian – Lebanese economic relations 1958 – 2000 came to confirm the depth of the relationship between the two counties and indicate the political tensions and the shadows it casts on economic relations. Perhaps the Syrian – Lebanese relations are among the strangest relations that exist between two countries or Even between two peoples , although it brings together a lot of special circumstances that are difficult to find in other countries , any event , even if it is fleeting , can be exploited in a way that harms the essence of the relationship in which interests may intersect between two ordinary countries that do not have any connection of historical weight or A specific geography , the Syrian – Lebanese relationship is , by virtue of history , concurrent with the emergence of the two states as political entities . This reason and others prompted me to choose this topic , which embodies the volume of trade and economic exchange between the two countries and clearly embodies the repercussions of the relationship , which passes from one period to another in a state of ebb and flow . This study sheds light on the economic relations between the two countries , although it is difficult to ignore the impact of the political conditions on them , as they are the main engine , and the decline in economic relations is only a reaction to the crisis policy in many cases . in writing this research , the researcher used the descriptive method of history , and he used an important number of sources that enriched the subject , such as the Lebanese – Syrian relations of the authors Antoine AL-Nashef and Khalil AL-Hindi , as well as the Lebanese – Syrian relations1985 -1943 issued by the Lebanese Documentation and Research Center and last but not least l hope this study will be successful in terms of providing information and facts to the lraqi offices and contributing to their enrichment and providing assistance to the lraqi researcher .
