The chief minister is likely to return on September 28, they said.
Banerjee said she was invited by industrialists, businessmen and the government of the two European countries. The dignitaries had visited the state during the Bengal Global Business Summit this year.
"I am going to Frankfurt and Milan to bring in more business and industry to the state. We will be holding two meetings - one in Frankfurt and another in Milan," she told reporters at the NSC Bose International Airport before leaving for Dubai enroute to Europe.
"We are benefitted by these kind of visits because they bring in more investments to the state," the chief minister added.
