Singh also held many bilateral meetings on the sidelines of the summit. He met Myanmar President U Thein Sein, Nepalese Prime Minister Sushil Koirala, Bangladesh premier Sheikh Hasina, Sri Lankan President Mahinda Rajapaksa and Myanmar's pro-democracy icon Aung San Suu Kyi.
Warning about the evolving threat of terrorism in the BIMSTEC region, Singh, in his address to the summit, sought stronger cooperation from the seven-nation grouping to effectively counter it, asserting that their security is "indivisible".
Singh travelled to Myanmar after a gap of nearly two years, in what could be his last foreign trip as Prime Minister.
