Prime Minister Narendra Modi on Sunday greeted US President Joe Biden and said that his contribution to strengthening Indo-US relations was critical and invaluable and India will look forward to work closely together.

The Prime Minister also congratulated Vice President elect Kamala Harris saying her success is pathbreaking, and a matter of immense pride not just for your chittis, but also for all Indian-Americans.

In a series of tweets, Modi said, "Congratulations Joe Biden on your spectacular victory! As the VP, your contribution to strengthening Indo-US relations was critical and invaluable. I look forward to working closely together once again to take India-US relations to greater heights."

Congratulating Kamala Harris, who is set to become first-woman Vice President of the US, he said, "Heartiest congratulations Kamala Harris! Your success is pathbreaking, and a matter of immense pride not just for your chittis, but also for all Indian-Americans. I am confident that the vibrant India-US ties will get even stronger with your support and leadership."

Modi's remarks came soon after Biden, the former two-term vice president and a Senate veteran, won the US Presidential elections to be the 46th President of the US. While Harris will be the next vice president, the first woman and the first person of colour to hold the office.
