After the nationalist turn, the PI saw it as one of its principle tasks to seek support from anti-colonial and anti-imperialist organizations and movements in other parts of Europe. It also wanted to demonstrate the crimes and horrors of Dutch colonialism in the Netherlands Indies to the outside world. By sending informal 'ambassadors' to Paris, Brussels and Berlin the Indonesian students established contact with prominent activists and anti-colonial movements, among whom Jawaharlal Nehru of the Indian National Congress, Messali Hadj of the Algerian Étoile Nord-Africaine, and activists of the Chinese Kuomintang. Indonesian students were also present at the pacifist Congrès Democratique International in August 1926 in the French town of Bierville, and at several meetings of the League against Imperialism from February 1927 onwards. Mohammad Hatta, who was the chair and most important of the Indonesian students, was appointed in the Executive Committee of the LAI, and thus acquired much prominence and an extensive international network.
