Pakistan today called on the United States to work closely with Islamabad to ensure that there is "no adverse fallout" of its new Afghan war strategy on Pakistan.
The Pakistani Foreign Ministry made the call after U.S. President Barack Obama announced he was sending 30,000 more troops to Afghanistan.
Pakistani officials have raised concerns that an influx of soldiers into Afghanistan could push militants over the border.
In Kabul, Afghan President Hamid Karzai's office said the government would "spare no efforts and cooperation" in implementing the goals of the U.S. strategy.
It also welcomed a timeline for the reduction of U.S. forces laid out by Obama as an opportunity to build up Afghan security forces and self-sufficiency.
Meanwhile, NATO Secretary General Anders Fogh Rasmussen said alliance members and their partners were ready to send at least 5,000 more soldiers to the Afghan mission.
"I can confirm that the allies and our partners will do more, substantially more. In 2010, the non-U.S. members of this mission will send at least 5,000 more soldiers to this operation and probably a few thousand on top of that," Rasmussen said.
There are some 70,000 U.S. troops currently in Afghanistan, plus around 42,000 drawn from more than 40 other nations.
In a statement emailed to media, the Taliban said Obama's plan to send extra troops to Afghanistan would only strengthen the group's resolve.
