Not a long time ago, similar youtube video with Russian subtitles appeared with a phone conversation of a Lithuanian (where I'm from) ambassador in Azerbaijan having a conversation with another official. This was as well with a goal to discredit Eastern Partnership (a cooperation agreement between the EU and several post soviet states).

One of the conclusions: diplomatic lines in many countries close to Russia are tapped by Russians. Ironic that Snowden is taking refuge in a country which has even less regard for privacy than the US. Not saying he had a choice..

On another note, not completely clear from the audio why the US diplomat is saying 'fuck the EU'. Wouldn't be surprised that EU is not being effective in making hard decisions in helping solve the Ukraine crisis.. causing disappointment among US diplomats. EU should be taking the lead in this IMO, but it's possible it's hugely ineffective due to lack of power (EU is not a state, it has to get a mandate to do things from member countries).

It's just a speculation, however.
