Washington:  US has welcomed the formation of the joint military working group by Afghanistan and Pakistan to "lower tensions" and safeguard the local population along the Af-Pak border.
"The United States supports the decision by Afghanistan and Pakistan to form a joint military working group to address recent incidents along the Afghanistan-Pakistan border," State Department spokesperson Victoria Nuland said.
"We call on both sides to continue to engage cooperatively to lower tensions on the border and to ensure the protection of the local population in the border regions," she said in a statement.
Nuland said last year has been one of real progress in the relationship between Afghanistan and Pakistan.
The signing and implementing of the Afghanistan-Pakistan Transit Trade Agreement and the formation of the Joint High Peace Commission are just two examples of the "positive and mutually beneficial advances in the countries' bilateral relationship," she said.
"We hope that the joint working group will continue this record of productive, diplomatic engagement," Nuland said.
