"Legitimizing more sanctions is a wrong way forward for the world. I have hopes that some future meetings between [US President Donald] Trump and [Russian President Vladimir] Putin will help to find a mutually agreeable way forward," Sussman said.
The lawmaker also called for lifting the Ukraine-related sanctions as soon as possible since Russia had already fulfilled all obligations stipulated by the Minsk accords on crisis settlement.
"I believe those sanctions should be lifted as soon as possible. Besides, I do believe that those sanctions were applied incorrectly and they should not have been applied in the first place. Secondly, from what I can see, Russia has done what it was required for lifting the sanctions," Sussman said.
Russian-US relations deteriorated in 2014 following the eruption of the Ukrainian crisis and Crimea’s rejoining with Russia. The United States and its allies introduced sanctions against Russia over its alleged interference in the Ukrainian internal affairs, while Russia denied all the allegations.
If passed, the Senate's sanctions bill will target Russia's defense, intelligence, mining, shipping and railway industries and restrict dealings with Russian banks and energy companies.
Also on Thursday, German Foreign Minister Sigmar Gabriel and Austrian Chancellor Christian Kern condemned the US bill on new sanctions against Russia.
