The Government of the Federal Republic Adopts a Declaration of Principles Regarding the Recognition of the GDR by Third-Party States after Discussion of the Hallstein Doctrine owing to the Recognition of the GDR by Cambodia, among others, and Freezes Relations with Cambodia

On May 20 [1969], according to the Bulletin, he [Federal Foreign Minister Willy Brandt] also explained before the Foreign Affairs Association [Gesellschaft für Auslandskunde] in Munich that the modus vivendi between the two parts of Germany is something that began with a minimum of consensus and needs to be patiently developed further. It will also not be able to exclude the difficult sphere of international relations, which used to be treated with the surgical scalpel of the so-called Hallstein Doctrine in a supposedly radical, but in any case rather undifferentiated, manner. A few words on this problem are in order in view of the occasion. Two countries, Iraq and Cambodia, have considered it advantageous to recognize the GDR diplomatically. The government of the Federal Republic has responded to this. At first glance, its responses might seem like an automatic application of an outdated doctrine, but such a view would be wrong. The two cases need to be judged separately, and exclusively from the position of the interests of our German policies, which are directed toward understanding and negotiation. In assessing the relations of other countries to the GDR, we see two aspects as having great significance. First, the form is of essential importance. If it implies a sanctioning of the division of Germany under international law and is lacking any positive reference to German reunification, then of course we cannot accept it. Second, independent of the form, we must examine whether an unfriendly act is being committed against us by way of motives and timing that would have to be viewed as compromising our inner-German efforts. In other words, recognition of the GDR by third-party countries will have to be viewed by us as an unfriendly act, especially as long as the GDR does not modify its intransigent and malicious attitude in its inner-German relations. Furthermore, it is logical that the inner-German rapprochement that we are seeking, the development from inner-German confrontation to inner-German cooperation, would continue in the international sphere. We do not want to isolate our compatriots in the GDR from international exchange. The opposite is true. […]
The government of the Federal Republic unanimously passed the following resolution on June 4, according to the Bulletin: “1. Based on the declaration of the government of the Federal Republic of May 30, 1969, the federal government has resolved to recall the German ambassador in Phnom Penh and to discontinue the activities of the German Embassy there. Economic and technical assistance shall be limited to the completion of the treaties already concluded; no new agreements are to be concluded. 2. The actions of the Iraqi and Sudanese governments as regards the German question have for the time-being destroyed any prospects for a normalization and improvement of relations between the Federal Republic of Germany and these countries, although positive signs had existed initially. 3. The federal government will not let itself be deceived by the attitude of the governments in Baghdad and Khartoum as regards its friendly feelings toward the Arab peoples. Rather, it will continue its efforts to promote and reestablish good relations with the Arab states, to the extent that they are willing. The special aid program for Palestinian refugees, which was successfully introduced, shall be continued.”
