India has been sceptical about Pakistan's latest steps to dismantle militant groups, with Indian officials calling the action cosmetic.
Ami Bera, the Chairman of the House Foreign Affairs Subcommittee on Oversight and Investigations, also urged China to play a constructive role by lifting its veto over UN Security Council resolution to designate Pakistan-based terror group Jaish-e-Mohammed (JeM) chief Masood Azhar a global terrorist.
Bisaria had left last month as a crisis gripped the region following the intrusion of Indian Air Force jets into Pakistani airspace following the killing of Indian troops in a suicide blast in India-occupied Kashmir.
Kumar said a recent United Nations statement also called for "perpetrators, organizers, financiers and sponsors of terrorism to be held accountable and brought to justice".
"The widespread presence of terrorist camps in Pakistan is a public knowledge within and outside Pakistan", he said.
"Pakistan has failed to take any credible action against Jaish-e-Mohammed and other terrorist organisations, which continue to operate with impunity from Pakistan", he added.
India had recalled HC Bisaria for consultations on February 15, a day after the Pulwama blast. It also says shut a number of facilities and frozen assets of several outlawed organizations.
"This government will not allow Pakistan's land to be used for any kind of outside terrorism", Khan said while addressing a rally in southern Pakistan.
"India hasn't shared yet any actionable information and proof against anybody", he added.
India said its air force hit a terrorist training camp and killed "a very large number" of militants.
Speaking about Thar's coal reserves, he said that the natural resources of the area would certainly change Pakistan. India said it lost only one aircraft.
Pakistan claimed it downed two Indian jets, and rejected IAF's assertion that a F-16 aircraft was shot down by it during the dogfight.
