Several Buddhist monks chanted prayers during which Modi closed his eyes and kept his hands folded.
Speaking at the event, Wickremesinghe thanked Modi for being the chief guest at the event.
“Proud to host Vesak Day celebrations in Colombo. I want to thank Prime Minister Modi for being the chief guest during the celebrations,” Wickremesinghe said.
“Teachings of Buddhism are relevant in today’s world.
Buddhism shows a moderate path and need to consolidate social justice,” he said.
Later today, Modi will inaugurate a hospital built with India’s assistance of Rs 150 crore.
He will also address Indian-origin Tamils against the backdrop of India’s insistence that Sri Lanka should undertake devolution of power to the ethnic community as part of the reconciliation process.
Modi arrived here yesterday on a two-day visit which is mainly aimed at reinforcing the traditional connect between India and Sri Lanka at a time when China is seeking to make inroads in the island nation.
