"As you celebrate Pakistan Day, know that the United States stands with you," Clinton said in a message issued on the occasion.
"I join President Obama and the people of the United States in congratulating the people of Pakistan as you celebrate the anniversary of the signing of the Lahore Resolution this March 23, which laid the foundation for the creation of Pakistan," she said.
The US and Pakistan are united by shared values, common interests and mutual respect, she said.
"We are constantly striving for greater tolerance, to enforce the rule of law and uphold the principles of democracy in both our countries," she added.
"As Mohammad Ali Jinnah said the story of Pakistan, its struggle and its achievement, is the very story of great human ideals, struggling to survive in the face of great odds and difficulties," Clinton said.
"These words ring true today as Pakistan works to fulfill the vision of its founders," Clinton said.
"We join the people of Pakistan in honoring these ideals and the valiant sacrifices the Pakistani people are making every day in the fight against violent extremism," she said.
"We remember the message of hope, courage and confidence the Quaid-e-Azam expressed to the Pakistani people and we continue to support your efforts to strive for a more peaceful and prosperous Pakistan," Clinton said. PTI LKJ
