Future territorial claims

Another of the treaty's important provisions was Germany's confirmation of the by now internationally recognised border with Poland, and other territorial changes in Germany that had taken place since 1945, preventing any future claims to lost territory east of the

). The treaty defined the territory of a 'united Germany' as being the territory of East Germany, West Germany, and Berlin, prohibiting Germany from making any future territorial claims. Germany also agreed to sign a separate treaty with Poland reaffirming the present common border, binding under international law, effectively relinquishing these territories to Poland.

Russian claims of unwritten assurances

The treaty does not mention NATO membership prospects of any other countries, as none of them has been a party to the treaty, while only four out of the fifteen NATO member states at the time have been parties to it. Some commentators, such as Stephen F. Cohen, as well as

in 2008, have advanced in later years the interpretation of a comment allegedly made by US Secretary of State,

, to the effect that NATO would expand "not one inch eastward" in a unified Germany, as applying instead to Eastern Europe; neither has such a provision been included in the treaty, nor any of the parties has proposed or demanded its inclusion, and neither a recording nor written minutes of Baker's comment exist. In 2014, Gorbachev said that the assurance only pertained to East Germany, and that the resulting agreement was upheld by NATO. His main aide in these negotiations,

Eduard Shevardnadze Eduard Ambrosis dze Shevardnadze ( ka, ედუარდ ამბროსის ძე შევარდნაძე; 25 January 1928 – 7 July 2014) was a Soviet and Georgian politician and diplomat who governed Georgia (country), Georgi ...
