Obama said this in a letter he sent to new Pakistan envoy in Washington, Husain Haqqani. "I will continue to press for a US policy that demonstrates a commitment to the people of Pakistan and a more effective approach to foreign assistance to promote democracy and roll back the forces of extremism," the Daily Times quoted Obama as writing in the letter.
He said, "Pakistan remains a critically important ally in the fight against Al Qaeda, a reason why I have been proud to support significant investments in its economic development over the last several years."
Recognising the 'sacrifices' Pakistan had made in the fight against terrorism, Obama said that more steps were needed to combat terrorists in its tribal areas.
In his letter, Obama also congratulated Haqqani on assuming his diplomatic assignment and vowed to work for advancing "critical partnership" between the two nations.
