The Greens have argued that fugu fish is reputed to be a dangerous delicacy that requires specialized chefs, who come mainly from Asia. Increasing restrictions on work permits are making it difficult for restaurants to recruit such specialists. The Shanghai Fugu Agreement provides specific international rules for Fugu certified cooks. Later, the Greens explained how this text found its way into the official document: in a final night session of the negotiations, the Greens presented a demand for Hesse to join the “Shanghai Fugu Agreement”. This was accepted by their tired social democratic colleagues and became official state policy. The Greens argued that fugu fish was known as a dangerous delicacy that required specialized chefs mainly from Asia. Due to increasing restrictions on work permits, restaurants have struggled to recruit such specialists. The Shanghai Fugu Agreement is expected to provide specific international rules for Fugu certified cooks. However, the agreement was absolutely fictitious, as fugu is not served in Germany at all. However, neither the Social Democrats were discovered as a joke during the nightly negotiations, nor later by officials or the press who reviewed the coalition agreements. It took years for it to turn out that the deal was a joke.
This agreement stipulates that “cases of coupling of work and residence permits are unanimously considered to be settled (Shanghai Agreement of 3.11.1974).” (Page 108, section 2.4; engl. “Cases of coupling between work permits and residence permits are deemed to have been resolved (Shanghai Fugu Agreement of 3.11.1974).) In 1984, the new Greens were preparing to enter a German regional government for the first time in their history. The prime minister of the Green Cabinet in German history was to be Joschka Fischer, who later under Chancellor Gerhard Schröder became Foreign Minister in the Federal Government. The 1984 Hessian Coalition, led by Prime Minister Holger Börner, was to be based on a formal agreement in principle negotiated by both sides.  The Shanghai buffer agreement is a fictitious international agreement that “Die Grünen” sang by the party in 1985 in the coalition agreement for the formation of the first red-green regional government in Hesse. In December 1985, the SPD and the Greens agreed in Hesse on the formation of the first red-green coalition at Land level. The Prime Minister was SPD politician Holger Börner, Environment Minister of the Greens Joschka Fischer, the first Green State Minister in the history of the Federal Republic of Germany. The government`s work was based on a coalition agreement negotiated between the parties.
In a round of nightly negotiations, a clause was added, at the request of the Greens, which indicated the so-called Shanghai Convention of 1974 and which, according to the Greens in 2004, provided for accession to this convention: in fact, tampons cannot be prepared in Germany – both the so-called problems with restaurant staff and the bowling agreements themselves were a free invention of the Landscape of Hesse. . . .
