Abstract
The article analyzes trade and investment relations between Kazakhstan and the Central Asian countries. The objective of this study is to conduct an in-depth review and evaluation of Kazakhstan's economic relations with Central Asian states. The tasks were carried out using methods including comparative statistical analysis, graphical methods, calculation of correlation coefficients and regression. The analysis showed a moderate positive correlation between the GDP of Kazakhstan and the Central Asian countries and a very close economic relationship. The study shows the importance of Kazakhstan's foreign trade turnover with the Central Asian countries. The issues of trade turnover between the countries are revealed, which reflect the influence of global and regional economic factors. Trade relations between Kazakhstan and Uzbekistan, and to a lesser extent Kyrgyzstan, remain steady and continue to expand, whereas commerce with countries like Tajikistan and Turkmenistan is comparatively limited, though gradually increasing. The shows that investment ties are developing at a new pace, though large foreign countries remain key investors. In the long term, Kazakhstan has significant potential to strengthen investment cooperation. Achieving this will require addressing political and economic instability, improving legal frameworks, and reducing corruption to create favorable conditions for direct investment inflows.
