The government is also in the final stages of framing a National Security Policy that will help it effectively combat militancy and eradicate extremism, he said while addressing senior civil and military officers participating in a course at the National Defence University here.
The government initiated steps for a dialogue with militants in light of decisions made during an All-Parties Conference but a US drone strike disrupted the process, he said.
"We want a durable solution of the menace of terrorism and the use of force will only be our last resort," Khan was quoted as saying in a statement issued by the Interior Ministry.
Pakistan has categorically communicated to the US that drone strikes are counter-productive and must immediately be stopped. "This continues to be an irritant in the Pakistan-US relationship," he said.
The new National Security Policy will have three components - "secret, strategic and operational", he said without giving details.
The government will make all-out efforts to enhance the operational capability of law enforcement agencies and the National Counter-Terrorism Authority (NACTA) will be the focal point for counter-terror efforts, Khan said.
A Joint Intelligence Directorate will also be established under NACTA for intelligence analysis and coordination among intelligence agencies.
