No, there is no such thing in Russia (well, you can probably find it big shops, but this sort of tea is almost unknown in Russia). At least there is no tradition that I know of drinking this kind of tea in Russia. The name "Russian Caravan" is curious, as in fact this is a sort of Chinese tea. As Wikipedia says the name originates from the 18th century camel caravans that facilitated the transcontinental tea trade from tea-producing areas (namely India, Ceylon and China) to Europe via Russia.
