Moron is deliberately lying withholding context. Baker's comment was in regard to only East Germany, in negotiations on the re-unification of Germany which resulted in the 'Treaty on the Final Settlement with Respect to Germany'.
Gorbachev, the President of the Soviet Union at the time said there was no promise not to enlarge NATO eastward past Germany. Former Soviet Foreign Minister, Eduard Shevardnadze also agreed, there was no limit on NATO enlargement.
No expansion of NATO eastward only covered East Germany. That's why there is a treaty-Treaty on the Final Settlement with Respect to Germany, which states NATO troops would not be stationed in former East Germany.
Gorbachev, the head of the Soviet Union confirmed this in later interviews, that there was no promise, since NATO expansion past Germany was never brought up in discussions.
The topic of “NATO expansion” was not discussed at all, and it wasn’t brought up in those years. I say this with full responsibility. Not a singe Eastern European country raised the issue, not even after the Warsaw Pact ceased to exist in 1991. Western leaders didn’t bring it up, either. Another issue we brought up was discussed: making sure that NATO’s military structures would not advance and that additional armed forces from the alliance would not be deployed on the territory of the then-GDR after German reunification. Baker’s statement, mentioned in your question, was made in that context. Kohl and [German Vice Chancellor Hans-Dietrich] Genscher talked about it.
