As one of the main leaders of the party and the country, Ubrich attaches great importance to party building. He advocated building the German Unified Socialist Party into a Bolshevik-style party guided by Marxism–Leninism. In the new domestic class struggle situation and international environment after the war, he emphasized consolidating and strengthening the unity of the party. After Stalin's death, 1953, 17 June, large-scale strikes and mass protests took place in the capital Berlin and other cities, opposing the government's wage and labor quota policies. Ulbricht and others accused R Herrnstadt, alternate member of the Politburo and editor-in-chief of the party newspaper, and W Zaisser, member of the Political Bureau and minister of public security, of forming an "anti-Party clique" and "using the enemy's attacks to create riots within the party", thus expelling them from the party. 1February, 958, ur Brichete criticized Sidwan, a member of the Political Bureau of the German United Socialist Party who attended the 20th Congress of the Soviet Union, for "opportunistically explaining the results of the 20th Congress of the Soviet Union" and accused them of demanding an "open policy" in the GDR and "attempting to change the party's line and leadership".

Ulbricht attached importance to the unification of Germany and Germany. 1957, he put forward the idea that two Germans should form a federation, stressed that the task of the federation was to bring the two countries closer together economically and culturally, and renounced the use of force to safeguard world peace. 1958, he further proposed that in order to eliminate the remnants of World War II and ensure that there would be no more wars from Germany, he advocated that Germany and Germany should withdraw from the military bloc and be unified into a peaceful, democratic and independent country. Since 1959, the Soviet Union put forward the proposal of making peace with Germany, that is, actually recognizing the long-term division of Germany, Ubud richter's formulation on the issue of German reunification has gradually changed. Ubri Heezen pointed out at the Sixth Congress of the German Unified Socialist Party in 1963 that reunification was unrealistic. He only asked Germany to establish normal relations and enter the United Nations at the same time. On the issue of West Berlin, Ubri Chet pointed out in June 1958 10 that the whole Berlin is located in the territory of the German Democratic Republic and "belongs to the sovereignty of the German Democratic Republic". 1On May 27th, 959, Ubri Chet announced that "all communication lines to West Berlin are under the jurisdiction of the sovereign German Democratic Republic." 1967, he agreed that West Berlin should become a "demilitarized free city".

1960 After the death of President Pique in September, the People's House established the State Council of the German Democratic Republic in the same year according to the proposal of the German United Socialist Party, and unanimously elected Ur Brichete as the chairman of the State Council. He held this position until his death. In leading economic work, Ubri Chet emphasized the better use of socialist economic laws, the improvement of labor productivity, the continuous improvement of management methods, and the improvement of the material and cultural level of working people. In view of the slow economic growth and inefficiency in East Germany in the early 1960s, he pointed out that the traditional economic management was outdated. In the 1960s, the GDR carried out economic reforms, implemented a new economic system of national economic planning management, expanded the authority of enterprises, implemented an economic leverage system with profit as the core, and used more economic means to manage the economy. However, due to the failure to properly handle the relationship between market mechanism and planned adjustment, the understanding within the party was not unified, and various difficulties and obstacles were encountered, which stopped in the 1970 s.

After the socialist relations of production were basically established, Ubri Chet paid more attention to discussing the theoretical problems of socialism. He believes that socialism is "a relatively independent social form in economy". In addition, he advocated the extensive development of socialist democracy, and the decision-making of major political issues must be discussed in depth through collective discussion. He attached great importance to studying the history of the workers' movement and summing up historical experiences and lessons. In order to commemorate the 20th anniversary of the founding of the German United Socialist Party, he presided over the compilation of the eight-volume History of the German Workers' Movement from 65438 to 0966. Over the years, he often said that studying history is his "third profession" and "history is the master of reality".

At the end of 1960s, under the leadership of Ubri Chet, East Germany formulated a new socialist constitution, which legally affirmed the achievements of the working class and its allies in socialist revolution and construction under the leadership of the Party.

197 1 On May 3, 2000, he resigned as the first secretary of the Central Committee and only took the honorary position of the chairman of the German United Socialist Party. Since then, due to the deteriorating health condition, Ur Brichete rarely participated in public activities. 1973 suffered a stroke on July 24th and died on August 30th of the same year.
