Dushanbe, July 30 - Pakistan, Afghanistan and Tajikistan Thursday vowed to cooperate in the fight against terrorism and organized crime and also strengthen their trade, energy and communication ties.

Agreement on this came at a trilateral meeting between Pakistani President Asif Ali Zardari, Afghan President Hamid Karzai and Tajik President Emomali Rahmon at Varzob, a picturesque tourist resort some 40 km from here, APP news agency reported.

The three leaders, who also signed a joint declaration, discussed the prospects of further promoting friendly ties and cooperating on regional and international issues.

'Today we will write another page in the history of the region and bring the concept of regional ownership to the war in Afghanistan,' Zardari said at a joint press stakeout with the other two leaders after the meeting.
