Russian President Vladmir Putin, who did not speak about terrorism at the BRICS meet, came out strongly against the menace at the BRICS-BIMSTEC outreach meet.
Modi said a country in India's neighbourhood held links to "terror modules" around the world, which BRICS should strongly condemn. It nurtures a mindset.
Without mentioning Pakistan, Modi said that selective approaches to terrorist individuals and organisations would not only be futile but also counter-productive.
The Prime Minister also said that country nurtures a mindset that loudly proclaims that terrorism is justified for political gains.
"We have agreed to make the BRICS a strong voice on emerging regional and global issues", Modi told reporters.
To address the threat of chemical and biological terrorism, the BRICS nations also supported the need for launching multilateral negotiations on an worldwide convention to suppress acts of chemical and biological terrorism.
Earlier on Sunday, Modi also held bilateral meetings with Sri Lankan President Maithripala Sirisena and Bhutanese Prime Minister Tshering Tobgay. "Terrorism has become its favourite child, and the child has come to define the character and nature of parent", NDTV quoted Modi as saying.
While it named the Islamic State, Jabat al-Nusra, the Syrian Islamist rebel group that recently rebranded itself as Jabhat Fatah al-Sham, and other United Nations designated groups, it didn't call for action against Pakistan-based terror groups such as the Jaish-e-Mohammed that India holds responsible for the Uri attack that left 19 Indian soldiers dead. We hope to tap the huge potential for cooperation and the dividends this will bring, ' Indian Prime Minister Modi said of the joint initiative.
The report said Narendra Modi on Friday described the outreach of BRICS to the regional grouping BIMSTEC as "significant", triggering further speculation that India may be looking at BIMSTEC as an alternative to the dysfunctional Saarc which has been bogged down by Indo-Pak hostility.
Our response to terrorism must, therefore, be nothing less than comprehensive.
"In our own region, terrorism poses a grave threat to peace, security and development", Modi said in his remarks to BRICS leaders who met at a resort hotel in the western state of Goa.
But the leader of the world's second largest economy said the long-term forecast for BRICS members was positive as he called for more confidence-building measures.
He said the establishment of New Development Bank and the Contingency Reserve Arrangement are "signature achievements". A top official, entrusted with drafting the PM's speeches, told The Indian Express, "Ever since the government chose to isolate Pakistan globally, we have been working on his speeches and trying to come up with innovative ways to describe Pakistan's links with terrorism".
"In this respect, we need to deepen the security cooperation between our National Security Advisors".
I join 1.25 billion Indians in once again extending a very warm welcome to all of you in Goa for the eighth (8th) BRICS Summit.
With the expansion of the BRICS agenda, the council also emphasised on the need to enhance business cooperation in agriculture by way of sharing of best practices among members.
