The adviser’s statement to the US State Department Derek Chollet is quoted by the Associated Press.
On Thursday, a senior US official expressed serious concern about the activities of the Russian PMC Wagner and its alleged attempts to recruit soldiers in Serbia and other countries.
"I don’t know if there are concerns (in Serbia), we talked about our concerns and we are looking forward to working with the government here in Belgrade and elsewhere where Wagner is active to put an end to their activities," he said.
Chollet also stated that Wagner's PMC "in action in terrible ways throughout the world, whether it is in Libya, the Central African Republic or right now in Ukraine."
The AP added that the company boasted of its presence in Serbia, the only European country besides Belarus that has not joined international sanctions against Russia for its war against Ukraine. The group reportedly announced the opening of its offices in Belgrade, which was later denied.
Valeriy Klochok, the head of the Center for Public Analysis "Vezha", believes that the creation of various PMCs by the Russian command was a pretext for the West to transfer tanks to Ukraine.
