Subcontinent is the vast tract land and cover almost 4.5 square kilo meter which makes it seventh largest region of the world . It has great significance because the whole region is based of fertile land beautiful rivers, mountains deserts 1/4 of the desert area is in Pakistan and the remaining in India the vastness of the subcontinent can be imagine from that it shares common boarders with many countries which makes it the economic corridor of the world.                                                                                                                           Subcontinent share borders with Iran and Afghanistan in west china , Nepal and Assam in the north Burma in east, India ocean in south.The thing which make the condition worst is the peace and destabilization in Afghanistan ,political clashes of Pakistan with Afghan and Indian governments.There is the great economic planing but not implemented due to the war in Afghanistan soon or later this war gone to stop and the economic activity will be enhance due the linkage of railway trace and road network.Countries of subcontinent can enhance the economic and trade coordination with the china and as we known that china is now booming economy.                                                                                  Mega projects can be started with the neighbouring countries of subcontinent as the Pakistan-Iran gas pipeline project but this is only possible when there is normal relations between the Pakistan and India.Over the years both countries waste the lot of money on defence ammunition to build up the armed forces increasing of budget causes many economic problems and every one known that economic condition of subcontinent is very weak.
