Kenneth I Juster, a top aide of United States President Donald Trump, is set to be America's new ambassador to India, the White House said today.

Juster, who is the Deputy Assistant to the US president for International Economic Affairs and Deputy Director of his National Economic Council, would replace Richard Verma if nominated and confirmed by the Senate.

"Ken Juster's move to Indian Ambassador is because he is extremely qualified for the position," White House deputy spokesperson Lindsay E Walters said.

"Ken has a strong and positive relationship with everyone in the White House, including the president," Walters said.

The move has been welcomed by widely respected Ashley Telis, the top India expert in the US.
