With the date of troop withdrawal from Afghanistan in 2014 approaching，the links between Central Asia and South Asia were even closer，though economic and trade cooperation did not see much improvement because of the intensification of power competition and instability in regional situation. In 2014，relations between Central and South Asia will enter a new phase of adjustment，since the new changes in Afghanistan will surely affect the region’s future development. Only if countries in Central and South Asia as well as other relevant countries are able to strengthen mutual trust and carry out more dialogues，they will establish even closer relations of cooperation. Otherwise，it will be difficult to have any breakthrough in relations between Central Asia and South Asia. But in the long term，South Asian countries among which India plays a leading role will inevitably strengthen their cooperative relations with countries in Central Asia.
