Later Chief Minister Mamata Banerjee told reporters that "we want more and more investment to come to West Bengal".
Referring to her earlier visit to Singapore to woo investors, the Chief Minister there was a "good response received from there".
She said in today's business summit the response was "very good" and hoped that more investment would come to the state and strengthen the process of industrialisation.
"Industrialists who attended today's programme and interacted with me were all praise for the facilities extended by our government", she said. "I feel good at such a response from industrialists and want there will be more investment and development", Banerjee said.
