Terrorism was expected to figure on the agenda as heads of government of the five BRICS emerging economies gathered in the southern Indian seaside destination of Goa Saturday for a two-day summit.
BRICS comprises Brazil, Russia, India, China and South Africa.
Observers had expected India to use the summit to politically isolate Pakistan. India blames a deadly attack on one of its army bases in Kashmir in September on militants it claims are based in and supported by Pakistan.
Terrorism was a key issue in bilateral meetings between Indian Prime Minister Narendra Modi and heads of governments of China, Russia and South Africa on Saturday, India's Foreign Ministry spokesman Vikas Swarup said.
Russian President Vladimir Putin had agreed with Modi that there should be zero tolerance for terrorism and Chinese President Xi Jinping said terrorism was a scourge for the entire Asian region, Swarup said at a briefing after the talks.
South African President Jacob Zuma expressed support for India's push for a comprehensive convention on international terrorism at the United Nations.
The BRICS leaders started their summit with an informal dinner hosted by Modi.
BRICS leaders are scheduled to meet with the heads of state of Bangladesh, Bhutan, Myanmar, Nepal, Sri Lanka and Thailand, in a wider outreach after their leaders' retreats and plenary session Sunday.
Annual BRICS summits largely aimed at economic and financial cooperation were launched in 2009.
