France => Israel
China => Pakistan
Russia => Belarus
France did provide Israel with knowledge in the construction of nuclear power plants that were essential to their later development of the bomb, but by the time that Israel actually developed weapons (likely 1966) French-Israeli co-operation on nuclear power had ended.
No idea where you get the idea that Pakistan got is nuclear capability from China from. It's not true. It did get some nuclear power expertise from the UK though.
Russia has stationed Russia-controlled nukes in Belarus (just as the US stations nukes in 3rd countries), not given the weapons to Belarus.
