Every party that wishes to belong to the Communist International has the obligation of exposing the dodges of its 'own' imperialists in the colonies, of supporting every liberation movement in the colonies not only in words but in deeds, of demanding that their imperialist compatriots should be thrown out of the colonies, of cultivating in the hearts of the workers in their own country a truly fraternal relationship to the working population in the colonies and to the oppressed nations, and of carrying out systematic propaganda among their own country’s troops against any oppression of colonial peoples. 9 Every party that wishes to belong to the Communist International must systematically and persistently develop communist activities within the trades unions, workers’ and works councils, the consumer co-operatives and other mass workers’ organisations. Within these organisations it is necessary to organise communist cells which are to win the trades unions etc. for the cause of communism by incessant and persistent work.
