It is a very interesting video. Breakfast between the two most powerful peoples in the world. The most interesting part in this video is when the chef, maybe, pump the samovar with the boots, of course not his boots. It is new information for me. I have read quite a few about the Russian culture, but not a lot, but seems I missed something important. Pumping the samovar with the boots is a very old tradition in Russian.
When not in use, the fire in the samovar pipe was faintly smouldering. When necessary, it was quickly rekindled with the help of bellows. Although a Russian jackboot сапог (sapog) could be used for this purpose, there were bellows manufactured specifically for use on samovars. Wikipedia
Looks like the Russians really taking care to preserve their culture.
