Sorry, I forgot the capability of China. I mentally equated "putting anyone in space" with putting people into the ISS.
With China in the picture, the Soviet-only gap would be between Skylab and Shuttle, I guess?
China's first crewed mission in space on October 15, 2003, which carried Yang Liwei in orbit for 21 hours and made China the third nation to launch a human into orbit.
> Space Shuttle which retired from service in 2011.
> 30 May 2020 (crewed)
