In Cusotmlink_country where are you assigning value in Country variable ? I think you need to use param to assign value in Country variable .

 
bujjibujji

<apex:pageblockSection >
       <apex:outputLink id="optLink1" value="{!$Page.clubsByCountry}">India</apex:outputLink>
       <apex:outputLink id="optLink2" value="{!$Page.clubsByCountry}">America</apex:outputLink>
       <apex:outputLink id="optLink3" value="{!$Page.clubsByCountry}">Australia</apex:outputLink>
       <apex:param assignTo="{!Country}" name="countrySelected" id="countryId" value="Country" />
    </apex:pageblockSection>

 

I added here but i am not getting states in other visual force page.

Please take hint from the code below.Add debug to make sure that selected country is assinged in variable.

 

<apex:outputLink id="optLink1" value="{!$Page.clubsByCountry}">India

        <apex:param assignTo="{!Country}" name="countrySelected" id="countryIdIndia" value="India" />

</apex:outputLink>
<apex:outputLink id="optLink2" value="{!$Page.clubsByCountry}">America

         <apex:param assignTo="{!Country}" name="countrySelected" id="countryIdAmerica" value="America" />

 </apex:outputLink>
