BlackRock Chairman and CEO Larry Fink told CNBC on Wednesday he’s not trying to use his influence as head of the world’s biggest investment company to force corporate America to embrace his ideas for social change.

Fink sent a letter last week to the chief executives of the world’s largest public companies, calling for them to help improve society or risk losing support from BlackRock, which just surpassed $6 trillion in total assets under management in the latest quarter.

“I have had conversations pretty close to half the CEOs who received the letter, and I don’t believe they’re sucking up to me,” Fink told “Squawk Box” in an interview at the World Economic Forum in Davos, Switzerland. “They were very favorable.”
