This study examines the interactions among economic development, exports and imports for Mongolia in the period during 1982-2010. For that to test for the existence of a trend relationships among GDP, export and import, the theory of cointegration proposed by Engle and Granger (1987), Johansen (1988) among others has to be applied, using the multivariate cointegration approach proposed by Johansen. We found that no findings could be reached as to support the hypothesis of import-oriented hypothesis; however, we could conclude that the empirical findings suggesting that GDP and import have an indirect effect on the economic development of Mongolia.
