"Direct or indirect Import or transit of all goods originating in or exported from Pakistan, whether or not freely importable or otherwise permitted, shall be prohibited with immediate effect, until further orders. This restriction is imposed in the interest of national security and public policy," the DGFT said in a notification on Friday.
The ban takes effect immediately until further orders, the DGFT said, adding that any exception shall require prior governmental approval.
Tensions between India and Pakistan escalated following a terrorist attack near the town of Pahalgam in the Indian-administered region of Jammu and Kashmir on April 22, in which a group of armed Islamist militants killed 26 people. The terrorist-linked Resistance Front insurgent group claimed responsibility for the attack.
India blamed the attack on Pakistan and followed up with reducing mutual diplomatic representation, suspending the Indus Waters Treaty and closing the only functioning land border crossing between the two countries. Indian Prime Minister Narendra Modi gave the army operational freedom to decide on the manner, targets and timing of a response to the Pahalgam terrorist attack.
Pakistan responded by suspending all trade with India and closing its airspace to Indian flights. Pakistan's National Security Committee said the country would regard any attempt by India to divert the flow of the Indus River as an act of war. Pakistani Defense Minister Khawaja Muhammad Asif told RIA Novosti on Tuesday that Pakistan would reciprocate if India attacks.
