After reading this Ministry of Foreign Affairs letter carefully, we need to look at the advantages of Pakistan, India, and Afghanistan. One thing should also put in your consideration on august 5,2019 when India change the status of Kashimir and remove article 370 and enforce curfew in the valley; kill the peoples of Kashmiri and lockdown them in their houses. Pakistan is the first country that raised the voice of Indian atrocities against Kashmiri peoples. On August 7th and 8th, 2019, a very high-level talk was held in Pakistan, where all the Gov and establishments were involved and they made lots of decisions.
One of the main points that was made was that there should be no trade between India and Pakistan. India stops their side business with us after the Abhinandon event. Since then, Pakistan froze all trade with India, and after almost a year now, we have survived without a single business deal with India. Now the question is exciting here, why do we need to open the Wagha Border? The answer is that APTTA is a bilateral trade agreement signed in 2010 by Pakistan and Afghanistan that calls for greater facilitation in the movement of goods amongst the two countries. The signed Agreement permits Afghanistan trucks access to Wagah border with India, where Afghan goods will be offloaded onto Indian trucks, but it does not allow Indian goods to be loaded onto trucks for transit back to Afghanistan. If we are not fulfilling our Muslim brother agreements, then the upcoming project of CPEC will heavily use Afghan transit in the future, which will create a problem when we send goods to Central Asia or Russia via the afghan link. If Afghan doesn't care about Kashmiri's cause and still wants to trade with India, then we can't enforce our will on them; this is their choice, and as per Agreement, let them use our transit for their one-way business, So in the future CPEC project we don't lose much in our trade volume.
