DUBAI (July 02 2010): Etisalat wants outstanding land sales in its buy of Pakistan Telecommunications Co deducted from the deal value, a letter to the Pakistan government seen by Reuters showed, although an official rebuffed the idea. United Arab Emirates-based telco Etisalat has been locked in a dispute over the $2.6 billion buy of a 26-percent stake in the Pakistani firm since 2006, due to complications over land sales linked to the deal.
