Pakistan continues to push in trained terrorists from a large number of terror camps across the border into India, Defence Minister A K Antony said on Monday.
This was a matter of serious concern and steps are being taken to check this, he told reporters in Thiruvananthapuram.
"Even now, not only the terrorist camps are operating there, (but) there is continuous efforts to push a large number of trained terrorists into Jammu and Kashmir and India.
"It is a serious matter, it is a matter of concern to us. So to prevent that, whatever steps (are) needed we are taking," Antony said.
He said it would be difficult to improve ties with Pakistan unless it made "serious" and "sincere" efforts to dismantle the large number of terror camps on its soil.
The terrorist camps operating from Pakistan was the main impediment to improve India-Pakistan relations, Antony said.
As a policy, he said India was not for any confrontation with its neighbours. "We want to avoid strained relationships with our neighbours and to improve ties."
