The situation began to normalise in 2000, with Pakistan and Iran reinstating trade relations. In the wake of the 11 September attacks in the United States and the fall of the Taliban government in Afghanistan, the two countries began rebuilding their military ties. Over the years, diplomatic delegations have been exchanged, and Pakistan has agreed to sell military equipment to Iran. In addition, Pakistan has maintained strong military-to-military ties with Turkey, and would like to use these, as well as its Iranian connections, as a bridge to the new Muslim states of Central Asia.
