Economic benefits for Pak from India if it ends terror safe haven: Mattis

US Defence Secretary says the Trump administration is being very clear and firm in what it expects from Pakistan

Pakistan could have strong economic benefits from India if it realised that the "tide has shifted" and stop providing safe havens to terrorists on its soil, US Defence Secretary Jim Mattis said.

Mattis told members of the powerful Senate Armed Services Committee yesterday that the Trump administration is being very clear and firm in what it expects from Pakistan and is using all aspects of the government to bring about the change, working internationally.

His statement comes weeks after President Donald Trump announced his Afghanistan and South Asia policy in which he adopted a tough policy against Pakistan. It also came ahead of Pakistan Foreign Minister Khawaja Asif's talks with Secretary of State Rex Tillerson and other top officials of the Trump Administration.

"There are a number of lines of effort being put together now in Secretary of Treasury's office, Secretary of State's office, my own office, the intel agencies. We are also working with Secretary General Stoltenberg to ensure that NATO's equities are brought to bear," Mattis said responding to a question on why would Pakistan change its mind on terrorist safe havens this time.

Certainly, India has a role to play as a neighbour, and potentially a very strong economic benefit to Pakistan, if Pakistan can find a way to carry out its international responsibilities and end any kind of safe haven inside their country, he noted.

"There's a great deal that Pakistan can benefit economically, diplomatically, financially for its government; economically for its people; by finally sensing that the tide has shifted against this," Mattis said.

He said that the Trump administration believes that it would be highly difficult to sustain any stabilisation in South Asia, not just in Afghanistan, but certainly anywhere around Pakistan and India unless safe havens are removed.

Mattis was responding to questions from lawmakers who wanted to know why the administration believes that Pakistan will change its behaviour this time.

Trump has said that he would change the US approach to Pakistan, which continues to harbour militants and terrorists who target US service members and officials, said Senator John McCain, Chairman of the Senate Armed Services Committee.

"But we still do not know what specific steps the United States will take to convince or compel Pakistan to change its behaviour, or what costs we will impose if Pakistan fails to do so," McCain said.

Indeed, McCain said it is unclear to him if the administration believes any step or series of steps the United States might take will lead Pakistan to cease its support and sanctuary for certain terrorist groups, which has been a "feature of" its national security policy for decades.

Ranking Member Senator Jack Reed said if the mission in Afghanistan is to be successful, it is imperative to disrupt the external sanctuaries in Pakistan, which continue to provide the Taliban, the Haqqani network and other associated groups the ability to train, recruit, rest, refit and stage attacks without significant fear of interference.

"We have heard that the administration intends to change the relationship with Pakistan in order to compel action that supports our efforts in Afghanistan," Reed said as he sought details of tools available to press Pakistan to make more progress on these issues.

Pakistan, Mattis said has a "convoluted history" with terrorism. There can be little doubt that there have been terrorist groups that have used Pakistan as a haven for attacks outwardly, and not just towards Afghanistan.

"We've seen the attacks on India, as well. At the same time, probably few nations, perhaps none, have lost as many troops fighting terrorists as they have," he said.
