I think Pak-US and Pak-China relations are more important than Pak-Russia. The oil crisis is a stale topic. There has been barely any update on this matter except hike in price :P Triple check on economic crisis. But you should also prepare for US debt crisis, what role does US economy play in the international economics, and Pakistan's economic crisis (These aren't titles of essays. Just something you should be ready for). Good ol' judiciary is always in the periphery :P
