Technically, you can't say hello in Cyrillic because it is an alphabet used by several different Slavic languages like Russian and Ukrainian. I'll be happy to write out a few ways of saying "hello" in Russian using Cyrillic, though. :)
Привет - pri-vyet (used casually, basic equivalent of "hey" or "hi")
Здравствуй(те) - Zdrastvoy(tyeh) = hello (tack on the 'tyeh' to make it more formal)
Алло - Alo (how Russians commonly answer the telephone)
Transnistria has three official languages - Moldovan (basically Romanian written in cyrillic), Russian and Ukranian. Hence: Noroc! Privyet! Privit!
Iartă-mă. Romanian hasn't used the cyrillic alphabet for a very long time now.
STOP (cyrillic СТОП) or STOI (стой)
"China" is translated to "ะะธัะฐะน" in Russian.
