Study of Moho in Middle East and surrounding region is of great importance for geoscientists. The area contains parts of the Eurasian, Indian, African and Arabian plates as well as active tectonic structures which made it rich in geodynamic and tectonic interests. In this study we investigated Moho relief in the Middle East region using gravity and seismic data. Regarding the extent of the study area, spherical prism (tesseroid) modeling is used to calculate the gravity effect of the topography and crustal anomalies. Determining of Moho depth from gravity data is a nonlinear inverse problem. We inverted the gravity data using Uieda’s inversion method where the process was constrained by the available seismic data over the study region. The effect of topography and crustal sediments were excluded using global topography and crustal models. The resulting Moho relief is in accordance with plate boundaries and correlates well with the prominent tectonic features of the Middle East region. According to the results, the thinnest part of the crust found to be about 12 km in the Indian Ocean and the thickest part appeared in the west of Tibetan plateau with depths of about 54 km. In some parts of the study area discrepancies were seen between our results and Moho depths from seismological studies these differences are most probably caused by different approaches used in the different studies. Since we imposed smoothness by regularization on estimated Moho map, this can also be additional source of the discrepancies.

The subject of the study is the economic development and security space of the Middle East. The aim of the article is to identify the peculiarities of the development of the Middle East in the global economy and to identify conflict issues that destabilize the region and deepen instability. Methodology (method). To achieve the goal and solve the outlined tasks in the research process used general and special methods: historical-logical, analysis and synthesis, generalization and quantitative comparison, visual (tabular and graphical) (to visualize the results of the study). Results. The importance of development and stability of the Middle East region for the global economy is substantiated. The structural structure of the Middle East region is determined and the historical preconditions of its formation are detailed. The tendencies to geopolitical transformation of the region are confirmed. The main challenges for development and stability in the Middle East have been identified, including local conflicts, the growth of terrorist acts, and ethnic problems. Emphasis is placed on the Kurdish issue, which periodically becomes acute and unresolved. Local conflicts that destabilize the region, as almost all countries have sufficient resources to confront, are analyzed. It is confirmed that the countries of the region are increasing their military potential to ensure their interests. The countries of the Middle East are identified by the level of human development. It is confirmed that the conflict areas of the region are negative for human development in the countries, and the progress made is slowing down. It is established that the world economy also depends on changes in the economic and political situation in the region, due to trade wars between countries, the application of sanctions. As an example, the restrictions on US foreign trade policy against Iran and the practice of sanctions are considered. The growing role of the countries of the study region in the global economy, which is determined by the presence of deposits of natural resources, in particular, oil, has been confirmed. The regional distribution of world oil reserves and its production is analyzed. The impact of OPEC's daily oil production restrictions on the COVID-19 pandemic on the Gulf economy has been elucidated. Measures to be taken by Middle Eastern countries to support economic development and security policy in the region are proposed.

In spite of her troubled presidency at home and premature, ignominious exit from power, Park Geun-hye made serious attempts to bolster the main direction of the Republic of Korea’s (ROK) foreign policy toward the Middle East. A collaborative drive for accomplishing a new momentous boom was by and large a dominant and recurring theme in the Park government’s overall approach to the region. Park enjoyed both personal motivation as well as politico-economic justifications to push for such arduous yet potentially viable objective. Although the ROK’s yearning for a second boom in the Middle East was not ultimately accomplished under the Park presidency, nonetheless, the very aspiration played a crucial role in either rekindling or initiating policy measures in South Korea’s orientation toward different parts of a greater Middle East region, extending from the Gulf Cooperation Council (GCC) to Morocco.

The Russian-American relations have undergone many stages of conflict and competition over cooperation that have left their mark on the international balance of power in the Middle East. The Iraqi and Syrian crises are a detailed development in the Middle East region. The Middle East region has allowed some regional and international conflicts to intensify, with the expansion of the geopolitical circle, which, if applied strategically to the Middle East region, covers the area between Afghanistan and East Asia, From the north to the Maghreb to the west and to the Sudan and the Greater Sahara to the south, its strategic importance will seem clear. It is the main lifeline of the Western world.

The article discusses the features and main approaches of Turkish foreign policy in the Middle East. Particular attention is paid to the history of the development of Turkish-American relations. The causes of the contradictions between Turkey and the United States on the security issues of the Middle East region are analyzed. At the same time, the commonality of the approaches of both countries in countering radical terrorism in the territories adjacent to Turkey is noted. The article also discusses the priority areas of Turkish foreign policy, new approaches and technologies in the first decade of the XXI century.
