President Donald Trump said on Friday he would nominate Sergio Gor, one of his closest aides, to be the next U.S. ambassador to India, where he will oversee frosty relations that have worsened with the planned doubling of U.S. tariffs on India next week.

Gor, who is currently the director of the White House Presidential Personnel Office, would also serve as a special envoy for South and Central Asian affairs.

Trump said in a post on his Truth Social account that Gor would remain in his current position until he is confirmed for the India post by the U.S. Senate.

"Sergio is a great friend, who has been at my side for many years. He worked on my Historic Presidential Campaigns, published my Best Selling Books, and ran one of the biggest Super PACs, which supported our Movement," Trump said, lauding Gor's work in hiring staff for his second term.

"For the most populous Region in the World, it is important that I have someone I can fully trust to deliver on my Agenda and help us, MAKE AMERICA GREAT AGAIN," Trump wrote.

U.S.-India ties have been strained by Trump's trade war, with talks on lower tariff rates collapsing after India, the world's fifth-largest economy, resisted opening its vast agricultural and dairy sectors. Bilateral trade between the two countries is worth more than $190 billion.

Trump first imposed additional tariffs of 25% on imports from India, then said they would double to 50% from August 27 as punishment for New Delhi's increased purchases of Russian oil. Trump has not imposed similar tariffs on China, the biggest purchaser of Russian oil.

U.S. Treasury Secretary Scott Bessent on Tuesday accused India of profiteering from its sharply increased purchases of Russian oil during the war in Ukraine and said Washington viewed the situation as unacceptable
