The Secretary of State Summit of the three western powers on September 18, 1950 in New York City, supported Chancellor Adenauer's claim.
At the Treaties of Paris (Pariser Verträge), at which the Federal Republic of Germany was admitted into the North Atlantic Treaty Organization, the allied nations adopted the position which the three western allies had already confirmed at the Nine-Power Conference in London: that the Federal Republic had the exclusive right to act on behalf of the entire German people in matters of foreign policy.
[1] Over time, especially after the election of a social-liberal coalition led by Willy Brandt in 1969, the exclusive mandate was softened, as it severely limited the Federal Republic's domestic and international autonomy.
Starting in 1973, under the Ostpolitik policy, the Federal Republic took the line that the Democratic Republic was, de jure, a state within a single German nation which could also function legally within international law as a sovereign state, while reasserting that the Federal Republic was itself the sole legitimate representative of a continuing German Reich that remained otherwise without institutional organisation; thereby relinquishing any claim to be de jure the government of Germany as a whole outside of its own boundaries until such time as the two German states might be reunified.
A third, the so-called "umbrella state" theory, entails the existence of two fragment states under the umbrella of a single German nation that had been formed in 1871 and which had never actually been annihilated; this theory arose in the late 1960s and was maintained in a ruling of the Federal Constitutional Court of Germany of 31 July 1973 upholding the "Basic Treaty" by which relations between East and West Germany were normalised.
[3] With the admission of both German states to the United Nations in 1973, matters regarding the exclusive mandate were no longer relevant.
In addition, visitors from the GDR would receive a West German passport upon request, for example, in order to ease travel to the United States.

This continued until the capital of South Vietnam was captured by the pro-North Vietnamese government in its civil war on 30 April 1975.
At the time, both of the countries had disputed the claims of being the sole legitimate representative of all the Khmer people of Cambodia in the United Nations.
Since the end of the Six-Day War in 1967, Israel has occupied the Golan Heights in southwestern Syria, only to de facto annex it in 1981.
Eventually, the Syrian rebel groups took control of the country by early December 2024, causing the Assad regime to crumble.
Like the Syrian situation, Yemen is governed by two regimes claiming to be sole legitimate government of the Yemeni state amidst the ongoing civil war: The current government led by president Abdrabbuh Mansur Hadi which is currently recognized by Saudi Arabia, the United States and the United Nations and the Supreme Political Council led by the Houthi movement in Sana'a is recognized by Iran and a few countries.
The Southern Transitional Council, formed in 2017, seeks the restoration of the former South Yemeni state that was unified in 1990 with North Yemen.
