M.N.Roy and Borodin decided that Mexico should take the lead. Soon Socialist Party of Mexico was converted into the Communist Party of Mexico in an extra-ordinary conference held in November, 1919 in the city of Mexico. Carranza, President of Mexico, who was on friendly terms with Roy, approved the event to take place. So the first communist party in the world outside Russia was born. It was in this background that Lenin invited M.N.Roy to attend the second Congress of the Communist International to be held in Moscow in July-August, 1920. Roy landed in Moscow in May 1920 and was given a copy of Lenin’s ‘Preliminary Draft Theses on the National & Colonial Questions’. Roy had certain differences on some fundamental issues with the views of Lenin. Roy’s Supplementary Theses was also adopted by the Comintern alongwith Lenin’s theses. Roy, on behalf of the Communist International, played major part in formulating the policies and implementing the programme of building up communist movements in different countries of Asia, including India.
