Pak-US relations deteriorated in 2009 when as part of US espionage network, hundreds of the American CIA spies entered Pakistan under the guise of diplomats who began anti-Pakistan activities through their affiliated militants by supervising and guiding them.
China and Pak istan are indeed all-weather friends. Both have long been allies but Pakistan has leaned closer to China after its tense relationship with the United States, its major donor, was strained when US forces killed Osama bin Laden and the NATO attack on Salala check posts.
...In this regard, after having strong relationship with the United States for more than 60 years, a shift has occurred in Pak-US ties because of a number of reasons, and Pakistan has inclined towards the Russian Federation which also needs the latter.
The United States and Nato have shifted hundreds of troops, heavy arms and gunship helicopters to the Pak-Afghan border along North Waziristan and sealed it for all types of movement. Tribesmen living in the border areas report curfew in the Gurbaz area of Afghanistan’s Khost province and say that the US and Afghan authorities are carrying out house-to-house searches.
Americans, aware there can be no victory in Afghanistan or Af-Pak, are, in demonstration of muscle, persistently droning the Waziristan region. Rampaging anti Americanism is exponentially visited on the Pak army.
