Huntsman, a Republican, left the Utah governor's office in 2009, when former President Barack Obama named him as ambassador to China. Visit MarketWatch.com for more information on this news.
"The bonds between our people remain strong", Huntsman said in a video released by the embassy previous year.
Huntsman was governor of Utah from 2005 and 2009 and is rumored to be considering a run for the position.
"I humbly resign my office as United States Ambassador to Russian Federation, effective October 3, 2019", the letter reads. However, a source close to Huntsman toldCNN that decision is still up in the air, saying: "We shall see, it's been a long two years".
Huntsman's longevity as ambassador has been in question for months.
A Republican, Huntsman was Ambassador to Singapore under President George H.W. Bush.
Huntsman, who has served in the post since 2017, was directly involved in the case of Paul Whelan, an American corporate security director who was mysteriously detained by Russian authorities on suspicion of spying.
Huntsman also served as USA ambassador to Singapore in the early 1990s, as well as a deputy US trade representative under former President George W. Bush.
He also ran for the GOP's presidential nomination in 2012.
In November, the envoy revealed that he was battling cancer.
"Going forward, we must continue to hold Russian Federation accountable when its behaviour threatens us and our allies", he said. Huntsman visited Whelan when he was arrested two weeks after an alleged Russian spy, Maria Butina, pleaded guilty in a US federal court to trying to influence U.S. They deserve our endless gratitude. "No set or restart is going to help, just a clear understanding of our interests and values - and a practical framework for sustained dialogue".
