The US military is expanding its Central Asian supply routes to the war in Afghanistan, fearing that the routes going through Pakistan could be endangered by deteriorating US-Pakistani relations, The Washington Post reported.
Citing unnamed Pentagon officials, the newspaper said that in 2009, the United States moved 90 percent of its military surface cargo through the Pakistani port of Karachi and then through mountain passes into Afghanistan.
Now almost 40 percent of surface cargo arrives in Afghanistan from the north, along a patchwork of Central Asian rail and road routes that the Pentagon calls the Northern Distribution Network, the report said.
The military is pushing to raise the northern network?s share to as much as 75 percent by the end of this year, the paper said.
In addition, the US government is negotiating expanded agreements with Kazakhstan, Uzbekistan and other countries that would allow for delivery of additional supplies to the Afghan war zone, The Post said.
The United States also wants permission to withdraw vehicles and other equipment from Afghanistan as the US military prepares to pull out one-third of its forces by September 2012, the paper noted.
US President Barack Obama announced last month that 10,000 troops would leave this year and all 33,000 personnel sent as part of a surge ordered in late 2009 would be home by next summer, leaving a US force of some 65,000.
There are currently up to 150,000 foreign troops in Afghanistan, including about 99,000 from the United States. Obama has indicated a series of drawdowns until Afghan forces assume security responsibility in 2014.
