education in 1921, he became the London correspondent of ROSTA (later TASS), the Soviet news agency. He regularly wrote articles for the Party, the labour movement, and as a correspondent for the Soviet news agency as "C M Roebuck". At the 8th Congress of the CPGB, he was elected to the Executive Committee and Politburo but removed from the latter after six years membership when the 11th Congress in December 1929 took the CPGB on a left turn. Rothstein was "utterly against" the new line but found himself appointed as deputy head of the Anglo-American department of the Red International of Labour Unions and served in the post for 18 months, based in Moscow. From 1920 to 1945, he was press officer to the first Soviet mission in Britain, and then correspondent for the Soviet press agency TASS, in London, Geneva and elsewhere. He became an authority on Soviet history, economy, institutions and foreign relations and began to publish widely: e.g. The Soviet Constitution (1923), Problems of Peace (essays on Soviet foreign policy, 1936–8), Workers in the Soviet Union (1942), Man and Plan in the Soviet Economy (1948). Andrew Rothstein was President of the Foreign Press Association, from 1943 to 1950 and, after the war, was the London correspondent of Czechoslovakian trade union paper, Prace, a post he held until 1970.

In this period, he published A History of the USSR (1950) and Peaceful Coexistence (1955).
