U.S. Secretary of State Hillary Clinton arrived on an unannounced visit in Islamabad on Friday, to soothen the hurt feelings of Pakistanis following the death of Osama bin Laden.

It is the first such high-level visit of any US top diplomat to Pakistan after U.S. commandos killed bin Laden in an operation on May 2.

The Pakistan government has criticized the U.S. secret mission in Abbottabad, as a blatant violation of its sovereignty.

Pakistan has told the United States to split the number of military trainers that are stationed in the country.

Clinton told reporters in a recent meeting in Paris that Pakistan was a strategic necessity for the United States.

Clinton has also pushed Islamabad to act more positively to counter terrorism and described Pakistan as globally a good partner” in fighting terrorism.

We do have a set of expectations that we are looking for the Pakistani government to meet but I want to underscore, in conclusion, that it is not as though they have been on the sidelines, Clinton said in a news conference in Paris on Thursday. They have been actively engaged in their own bitter fight with these terrorist extremists, she said.
