A spokesman for the Nato-led International Security Assistance Force (Isaf) on Saturday said that the closure of Pakistan's supply route has not created serious logistical problems for the coalition in Afghanistan.

Isaf Spokesman Brig Gen. Carsten Jacobson said that the 130,000-strong coalition has re-adjusted it's logistical operation and the closure of Pakistani route only caused trouble for the first few weeks.

"We had to re-adjust logistical flow, but as it's today, nearing the end of January the logistical situation of Isaf is stable," Gen. Jacobson told TOLOnews.

The Pakistani government closed a key Nato supply route after Isaf forces killed two dozens of Pakistani soldiers in a border attack on November.

Nato says they have adjusted their logisti cal operation through alternative routes such as through Central Asia and via air.

"Well, we have seen two months. The critical face in re-adjusting logistics is always in the first weeks. That is obviously past. So Isaf has changed that logistical system and our supplies are secure and actually we have started re-building our stocks," he said.

The closure of Pakistani route, Jacobson says, leaves a negative impact on Pakistan's economy as hundreds of Pakistani who were involved have remained unemployed.

"It has economical impact on the Pakistan economy, and on Afghanistan's economy and from the point of view of the coalition, it is an important step towards normalisation in the relations.

"Of course Isaf has an interest that the ground lines are opened again but as I said logistically we are not dependent on it," the German general said.

The US Secretary of Defence Leon Panetta has said that his country pays $ 104m in a month to Afghanistan's northern neighbours for supplying its troops in Afghanistan. It's almost ten times more than what was paid to Pakistan.

Senior Pakistani officials have said that Pakistan considers re-opening the route for Nato convoys, however, certain taxes would be imposed on Nato commodities.
