Afghanistan's former President, Burhanuddin Rabbani, who leads a council tasked with starting peace talks with Taliban-led insurgents, held talks with Turkish government officials in Turkey in February.
A joint statement after those talks said Afghanistan and Turkey would work "with all concerned parties in promoting the peace process in order to ensure successful outcomes."
Afghan and Pakistani intelligence agencies suspect each other of secretly encouraging militant factions to launch attacks to destabilise each other's governments in the hope of winning greater influence once Western forces leave the region.
Turkey, the largest Muslim country in NATO, has troops in non-combat roles with NATO forces in Afghanistan, and also has well established military-to-military contacts with Pakistan.
While U.S.-led NATO forces have built up troops in Afghanistan there is also a search for a political solution.
U.S. President Barack Obama has promised to begin pulling out U.S. forces in 2011, and NATO has agreed to end combat operations and hand security to the Afghans by the end of 2014.
