Russian President Vladimir Putin said on Thursday he hoped Moscow could cooperate with Washington in a broader range of fields. "We have dialogue at the work level and on the level of the special services, the defense ministries, the foreign ministries. We achieve joint results," Putin said at a forum with scholars. "We have to expand our cooperation to other spheres." Putin also said that Moscow was not concerned about a US military build-up in the Baltic region. "We are analyzing it, watching this closely. Every one of their steps are known and clear to us," Putin said at a forum with scholars. "This doesnt worry us. Let them train there, everything is under control." Commenting on the chances of closing of Russias borders with rebel regions in eastern Ukraine, Putin said it would result in a "Srebrenica-like massacre", referring to the mass killing of Muslims during the 1992-95 Bosnian War. He said Europe was to blame for the Ukraine crisis and that only European powers could act to change the situation. Putin added that the International Olympic Committee (IOC) was being pressured by the US to prevent Russia from taking part in the 2018 Pyeongchang Winter Olympics. "We are seeing that the IOC is under strong pressure," Putin said at a forum with scholars. "It relies on advertisers, television channels, sponsors, and so on. And these sponsors are receiving unambiguous signals from certain American institutions."
