Russian Ambassador to the United States Anatoly Antonov said that Russian embassy is taking every possible step to solve the problem of Maria Butina’s detention in the US as soon as possible.
"There is nothing new in this case. The US intelligence services hunt for Russian citizens not only in the US, but also in other countries," Antonov said.
The US government announced on Monday that Maria Butina had been accused of conspiring to act as a foreign agent for Moscow. With the latest additional alleged crime, Butina is seen by US authorities as having materially acted as a foreign agent in addition to conspiring to be one.
Russian officials have been demanding consular access to Butina.
Butina, a longtime advocate of gun rights in Russia and a recent graduate of DC's American University, where she studied international relations, is believed to have worked with the US National Rifle Association (NRA).
Russia-US Summit in Helsinki
Russian President Vladimir Putin and his US counterpart Donald Trump did not make any secret arrangements at the summit in Helsinki, Antonov said.
"Vladimir Vladimirovich has told everything. There are no secret agreements reached at the meetings held in Helsinki, as far as I know," Antonov told reporters.
Trump was heavily criticized in the US after the Helsinki summit with no real grounds; Russia will try to help improving relations, he added.
"I have a feeling that some of them [US politicians and journalists] did not listen to what their president said, how he defended national interests… [Trump] will find himself in very difficult situation, but we will do everything possible to at least help our US partners. I think that we should find at least some small-scale joint projects at the first stage in order to break free from deadlock caused by contradictions and difficulties that we have," Antonov told reporters.
Issue of the US sanctions against Russia was not raised at the Helsinki summit between Russian President Vladimir Putin and his US counterpart Donald Trump, the sides discussed economic cooperation, Antonov said.
"The issue of sanctions as such was not discussed. The part of talks which I attended addressed the issues of economic cooperation," Antonov told reporters.
On July 16 Russian President Vladimir Putin held a first face-to-face meeting with US leader Donald Trump in the Finnish capital of Helsinki. The two parties have discussed the current state of bilateral relations along with pressing issues on the international agenda.
