Christie and Modi shared their experiences of using social media as a tool of governance. Christie told Modi, "I watch your usage of social media closely."
After the meeting with Modi, Christie took to Twitter to thank Prime Minister Modi and posted a picture of the meeting.
"@narendramodi enjoyed meeting with you this afternoon in NYC. Thank you for the invitation," he tweeted.
Christie is the third important visitor who called on Modi.
The prime minister had earlier on Friday met New York City Mayor Bill de Blasio and Director of the US National Cancer Institute, Harold Varmus.
