The US government has announced a major new aid package for Pakistan, with hundreds of millions of dollars to be spent on projects in Pakistan's energy and water sectors.
Hillary Clinton, the US secretary of state, announced the package at the start of a day-long "strategic dialogue" in Islamabad between American and Pakistani officials.
The money - part of a five-year, $7.5bn aid package approved by the US congress last year - will support a total of 26 projects.
Monday's meeting is the second such dialogue between the US and Pakistan.
The first, held in Washington in March, ended with promises of better co-operation between the two countries.
"We know that there is a perception held by too many Pakistanis that America's commitment to them begins and ends with security," Clinton said on Monday. "But security is just one piece of this vital partnership."
Dams and hospitals
Electricity is one of Pakistan's top priorities. A large chunk of the new US aid will be spent on new power supplies, including the Gomal Zam dam in Pakistan's Khyber-Pakhtunkhwa province, and several hydroelectric projects in Balochistan province.
Clinton said the US would also fund several solar and wind energy projects.
Pakistan's electric grid is chronically overtaxed, with hours-long blackouts common across the country. The Pakistan Electric Power Company reported earlier this week that demand for electricity outstripped supply by nearly 5,000 megawatts.
US aid will also be used to renovate three hospitals, in Karachi, Lahore and Jacobabad, to launch several agricultural programmes, and to expand access to clean water in Pakistan.
Monday's "strategic dialogue" follows Clinton's meetings on Sunday with Asif Ali Zardari, the Pakistani president, and Yousuf Raza Gilani, the prime minister. Clinton also attended the signing ceremony for an Afghan-Pakistan transit agreement, which will allow Afghan goods bound for India to travel through Pakistan.
After leaving Islamabad, Clinton will travel to Kabul, where donors will meet on Tuesday for the ninth international conference on Afghanistan in nine years.
