On this day, 35 years ago, on June 22, 1990 (May 30, 1990, the two German Houses formally ratified the national treaty. On June 22, 1990, the People's House of Representatives of the Democratic Republic of Germany and the Bundestag of the Federal Republic of Germany formally approved by overwhelming majorities the national treaty signed by the two governments in May 1990 on the establishment of an economic, monetary and social union between the two Germans. This treaty will come into effect from July 1. Public opinion believes that with this step, the door to German reunification has officially opened. At the meeting of the People's House of Representatives of the People's Republic of Germany on the 22nd, the ruling party believed that this treaty provided an opportunity to transition from a planned economy to a market economy and paved the way for unity, but the Democratic Socialist Party and the coalition 90-Green Party opposed this treaty. In the end, the People's House approved the treaty with an overwhelming majority. On the same day in Bonn, Prime Minister Kohl said at a meeting of the Bundestag that the West would continue to open up to the East. He hopes to discuss providing more economic and technical assistance to the Soviet Union and Eastern Europe at the upcoming summit of the European Community and Western industrialized countries. Green Ke and some Social Democratic Party members expressed opposition to the treaty. In addition, the People's House of the Democratic Republic of Germany and the Bundestag of the Federal Republic of Germany overwhelmingly passed a joint resolution on ensuring that Poland's western border with Germany would not be changed. The resolution reiterated that a treaty of international law will be adopted between unified Germany and Poland to finally confirm the direction of the border with Germany in western Poland as delineated by the Potsdam Agreement after the Second World War. Observers believe that the two German parliaments passed the resolution to allay Poland's fears that a unified Germany might one day make territorial claims to Poland, and thereby eliminate one of the difficulties among the external obstacles to German reunification.
