One China’s latest bombers, the Xian H-6K, is a development of their H-6 which itself is a license built Cold War era Soviet Tupolev 16. It debuted in 2007. The most recent version is the H-6N (debuted in 2019) which looks just like the H-6K, but can be identified by the refueling probe sticking out of the nose.
