Benaulim (Goa), (PTI) Seeking to further isolate Pakistan on terror, India will mount a major diplomatic offensive against it and push for stepped up cooperation, including support for a comprehensive global convention to tackle the menace, when it hosts the annual summit of BRICS, a 5-nation grouping representing nearly half of the world's population.

The summit, being attended by Russian President Vladimir Putin, his Chinese counterpart Xi Jinping and leaders of Brazil and South Africa, is likely to deliberate on a range of key issues including confronting threat of terror and boosting trade and investment.

Prime Minister Narendra Modi said the leaders will discuss ways to address "pressing international and regional challenges that stand in the way of our goals".

"I am optimistic that the BRICS Summit will strengthen intra-BRICS cooperation and advance our common agenda for development, peace, stability and reform," the Prime Minister said in a Facebook post.

The five BRICS countries represent over 3.6 billion people, or half of the world population and they have a combined GDP of USD 16.6 trillion.

India is likely to push for unity among the BRICS (Brazil-Russia-India-China-South Africa) members to remove the logjam at the UN on the Comprehensive Convention on International Terrorism (CCIT) for effectively dealing with terror. Initiated by India, the CCIT is stuck at the UN due to lack of agreement among its members about the definition of terrorism.

India is also expected to push for enhanced cooperation among BRICS nations in the area of counter-terrorism.

Preceding the BRICS summit, Modi is likely to raise the issue of terrorism with Putin and other leaders tomorrow when a series of bilateral meetings are slated at the seaside venue.

Addressing a press conference today, India's envoy to Russia Pankaj Saran, replying to a question on Russia's recent military exercise with Pakistan, said India expected Moscow to reflect on its concerns.

As the top leaders of the grouping meet within weeks of Uri attack by Pakistan-based terrorists, India will be forceful in its demand at BRICS Summit as also the BIMSTEC outreach meet being held the same day, for intensified efforts to tackle terrorism, including action against countries providing safe havens to terrorists and arming them.

"Representing nearly two thirds of humanity together, we hope to tap the potential for cooperation and the dividends this will bring," Modi said on the first-ever BRICS-BIMSTEC Outreach Summit.

India has made strong references both at UNGA as well as G-20 regarding Pakistan's continued support to cross-border terrorism. .
