Russia signed the 2014 Minsk accords while still sending troops into Ukraine
And they withdrew them when signing Minsk 2 in 2015. The agreement was brokered and signed by France and Germany, and signed by Russia and Ukraine. Ukraine failed to implement the agreement, which would have kept the separatist regions in Ukraine, but with greater autonomy. Years later Merkel said Germany only signed because they wanted to give Ukraine time to arm itself.
